Interesting thoughts:
Why is this one of the few games I have ever finished?
Is there a common thread between the finished games?
Does finishing or not finishing a game correlate to how much I enjoy the game?

Finished games include
Batman: Arkham Asylum
Arcanum
Deus Ex
Mass Effect
Oblivion (finished the main quest)

Factors contributing to finishing a game:
Length: 16-ish hours
Story: Mass Effect and Tomb Raider I wanted to see how the story ended. I didn't care about the story's end in any of the other games up there.
Mechanics: In a story game, there has to be enough variation and innovation mechanics-wise to keep my learning new things up to the end of the story. In Tomb Raider I found the parallel pacing done well. In Batman as well.

If a game is mostly about fun mechanics, like Deus Ex, I find no compelling reason to go through to the end. I'll just keep playing the earlier levels over and over, happily. With Oblivion, mods supplied that never-ending mechanical delight.

Tomb Raider had a good mix of main story/side missions, story/mechanics, action/puzzle, and open world/rails. I am not interested enough to go back to achieve 100% completion, nor to play the story again. But I sure enjoyed it start to finish.

Are you talking about the last one?

I never finished Deus Ex but bought it here to try it again.

Yeah the 2013 reboot.

Deus Ex - I thought the beginning up through HongKong was awesome. The rest was fine fitting and fun, but not as his as those early levels.

The reboot doesn't count!

Okay it does but there will really be only ONE Tomb Raider. They need to give the reboot a different name.

You're right. The originals counted. 1, 2, 3...

i usually refer to the reboot as tomb raider 2013

As pretty as the 2013 one is, it felt... shallow to me. Tried to feel open world and hide the Linear hallway. It only partly succeeded...

Then the cutscenes which didn't match well with the rest of the game, which jarred the experience...

At best i could only call the newest Tomb Raider an Okay game... Square Enix on the other hand considered it a failure when they only sold 4-6 million copies...

squeenix expected cod level of sales
they over estimated the popularity and marquee value of tomb raide which dropped hard since the late 90's

only a few titles can match cod in sales and tomb raider is not among them

( mostly mario titles gta and possibly halo forza and gran turismo )

Because after they add multi-player, it's where everyone wants to be and playing FPS right?

Actually i sorta wish they only sold 2-3 million instead of as well as they did after i played it. I gave my full opinions on the Tomb Raider section, but most of the time it didn't even feel right like Tomb Raider... Especially the cut scenes...

Huh. Do you have a source for that? I thought the sequel to the reboot was underway and the future looked bright for the rebirth of the series?

Nah, Squeenix pretty much pissed all over it at their conference.

I really liked the game and played it twice, not for achievements or anything, it was just a joy to play it, a nice mix of exploration and narrative. People bitched about the "tiny tombs", but sod it, it was a bloody enjoyable game not strictly TR, but judged n its own merits a I really liked it a lot.

Apparently the sequel is a M$ exclusive for an undetermined period, which puts it on my ban list till it gets an agnostic release.

It's a simple and nice-looking game, the typical game that people finish. They put the bar super low and they totally hit it. Great job.

any reason why dragon age origins is not in that list followed by neverwinter nights 1 & 2 .
Give unreal 2 a shot if you liked mass effect

I also finished Tomb Raider and I don't normally finish games (I also finished Arkham Asylum, but not ArkCity).

I liked the character progression, the feel of the game, the change in mechanics, the cinematic-ness of it, and the ability to pick it up, play it for 20 minutes and put it down.

I hope the next one improves vastly on the tombs, though.

Still making way through DA:O. Probably I will finish. but it will be a while.
