What fires me up is most 2D games with little guys running around pulling levers and stuff. I guess that's the feeling I wanted to get at with BQ.
It just doesn't work if the character is too big like Samus in the GBA Metroid games.
Here's a few screen shots I took of Exile. It's a relatively rich game. If you're curious about it, you can read more about its features
here. I prefer the C64 version over the Amiga version, and certainly over the AGA version which was way too zoomed in.

Here's a few screen shots I took of LaserSquad (with commentary).

Moonbase from RebelStar Raiders gives me a serious hard-on. You can put the cursor over objects and get a little description. The whole base has been layouted to function, it's not just a mishmash of corridors and rooms with crates. There's even a little park inside, with a functioning lawn mower. It's like one of those secret-base drawings you made as a kid - come to life... well, with ZX Spectrum graphics.
I love Dwarf Fortress screen shots too. Even if they don't directly show the history of the fort and dwarfs (which really means a lot to the player of the game), they do show some of the philosophy and passion the player had when layouting the fort. It's always interesting to see a screen shot which also tells things about the player.
