Not Spear of Destiny.
Hint: It's not an old game, but it can run on a 25 year old computer.

McPixel...3

Also, I think I'm gonna let someone else take my turn.

It is indeed. :)

Your (or someone else's) turn

I'll go:

small hint: there was a small series of games with these graphics/engine, so listing any of them counts.

Methinks 'tis time for another hint :)

Hm, you're probably right. I thought I killed the thread, but maybe the game is more obscure than I thought.

I'll give some hints that allow people to find it with some basic searches:

-The game (well, one of them) was named after the air force program that gave us the F-22.
-The games were part of a licensed deal series between EA and an open source intelligence company (starts with J, and it's in the titles), and they tend to be part sim part encyclopedia.

Well that made it pretty easy, I think :)

Jane's Combat Simulations: ATF - Advanced Tactical Fighters?

Bingo, that's it. Next time, I'll try not to pick such an obscure game...maybe.

I like seeing obscure games in this thread.
It's always nice to learn a bit more about videogames history.
Besides, it brings some extra challenge :)

Ok, next one!

I think it's less about it being an obscure game and more about there not being many old school flight sim fans here. The only (non-space) flight sim I personally might be able to guess just from screenshots is Comanche Maximum Overkill.

A more complete version of the above screenshot:

Dread Templar?

You got it, your turn!

Okay, Here goes

CyClones!
