We live in times where we have huge backlogs and way more games than we can play. It's simply not possible for me to play everything I own or to check everything that comes out. As such, I developed a few ground rules when it comes to gaming, kinda like red lines I will not cross. They are:

-If the game is on console, it's out.
-If the game needs a controller, it's out.
-If the game has required online components, it's out.
-If the game doesn't have a single player campaign of some sort, it's out.
-If it mentions "competitive" on the description, it's pretty much out.
-If the game uses Uplay, it's out.
-If the game uses Origin... I haven't tried the service yet, so I'd be willing to give it one chance, but I need a game good enough for me to bother installing it and nothing has interested me just yet.
-If the game is on steam... I didn't use to mind too much. But with the recent retroactively applied region locking making me lose all trust and GOG getting a lot of ex-steam games, I'm basically ignoring the service these days. A steam game isn't out right away, but it strongly puts me off.
- I haven't yet, but I intend to jump to linux on my next computer (probably next year) and a new "no linux, no buy" rule.

Do others here have similar filters when browsing games?

Do you mean console-exclusive?

Yes. Basically, if I need a console to play it, I have no further insterest on the game.

Ah, for a minute I thought it was "they released it on console so they must have dumbed down the graphics for PC" logic...

No rules for me other than my machine must meet requirements (so consoles and controllers fall into this, but only because I don't own them, and doubt I will).

- I feel like playing it

- If the game is exclusively for a platform that I don't use, it is out (iOS, post-PS2 consoles...).

I was going to say "DRM-free", but that isn't really true, as I have games with DRM too. But it severely lessens the interest rate, e.g. from the Steam sales I'm really looking only at Skyrim (Legendary Edition) for a cheap price, but may even pass that. I have zero interest to check what else there is being offered.

You could try Origin with those "On the House" games.

Your loss. Some of the most enjoyable games I've played over the last years were console exclusives. Shockingly there aren't that many in the current and last generation (especially good ones) but several ones I've played have easily become some of my all-time favourite games.

aside from "what do I feel like playing right now"

-I object to games with a mature rating so if I have reason to even think I wont like the game I won't buy it
-imho not enough games have the E rating so if I think I might like it (and it isn't to high priced) i'll get it

vote with your wallet and all that stuff

Mine is similar but a little more restrictive:

-If the game is on console, it's out.
-If the game needs a controller, it's out.
-If the game has required online components, it's out.
-If the game doesn't have a single player campaign of some sort, it's out.
-If it mentions "competitive" on the description, it's pretty much out.

-If the game isn't on gog or I didn't kickstart it, it's out.
-If the game doesn't work on mac (through wine or dosbox or natively), its out.

What for? Those on the house games are typically on my GOG library already. Or they are some multiplayer stuff I don't care about. I basically don't even bother looking at those on the house games anymore, to be honest. Perhaps. I've never been a console gamer, and the times I had a console around, I was not particularly impressed by their games. The one game that I really liked on PS3, Valkyria Chronicles, just came to PC anyway. I don't have the money or the energy to bother with several gaming machines that I can't use for anything else.

This. With the exception of Windows-only games (I purchase them despite not running that platform because I can run many of them on Linux, through Wine).

I don't really have hard filters. If there's a possibility I can run the game today or in the future, there's a chance I'll buy it. If the game seems awesome enough I'll buy it ASAP just to have the box (I preordered The Witcher 3 Collector's Edition despite running Linux and not having the chance to run the game until either they release a Linux version or Wine catches up and gets DX10/11 compatibility, because I figured the CE will be sold out quickly and I want all the crap that's bundled with it; statue, medallion, and whatever else is in there).

There are quite a few criteria though that are close to being filters. For instance, I'm very reluctant to buy (pay for) a game that is primarily or exclusively meant for online gaming. So I should say my interest into buying games is only for single-player games. Those games may have online gaming parts and I might even play them on top of the single-player part, but I wouldn't buy a game for its online gaming features.

The reason I can't call this as a filter though is that I have have bought the Unreal Tournament games from GOG. :) I bought them mainly for their music though. Other than those, I don't think I have bought any game which was mostly or solely intended for online gaming. Could be that I have bought some without realizing it, like some games I've bought in Humble Bundles.

Other than that, I consider online multiplayer games to belong to the free-to-play realm. I admit I've gotten quite a lot of gameplay and enjoyment out of e.g. TeamFortress 2, for which I haven't paid a dime (even with microtransactions). It tries to push me a bit to pay for it (e.g. to expand the inventory, or pay money for some weapons or abilities), but no, I'll do without. If it becomes too inconvenient to play without paying, then I'll just stop playing it.

I guess I am reluctant to pay for something that may disappear as soon as the publisher decides to cut off its multiplayer servers (ie. many EA games, I guess).

You misunderstood my post. I was just saying that if you wanted try a game with Origin to see if it matches your requirements, you need not buy it and regret losing your money if it doesn't work out.
