Raging Thunder 2 is a great 3d racing game can play online too has achievments leaderboards also check out
zenonia - rpg in the style of snes zelda
Super KO Boxing 2 - is free on promo
Carrom 3d - has 3d pool
Mystique - fps horror game
Bonsai Blast - Like zuma if youve played it, this is also free
Also worthwhile getting on the emulators available on marketplace which have a great catalogue of games already
Theres snes megadrive (genesis) nes gameboy mastersystem gamegear commodore capcom system 2. One problem is these rely on multitouch to work properly which unfortunately you will have to wait till september update to froyo 2.2 to work. Still nice to try them out at the moment though. You can get the roms from your pc just type in snes roms etc into google then transfer them to your dell streak memory card via usb.
Also know that theres a playstation emulator on the way.
Quake 2 and Quake 3 look good but not directly available of the marketplace, you have to download emulators then transfer the original game onto the streak so is a bit awkward but can be done.
The quake 3 emu is under kwaak3 on google, quake 2 emu is just under quake2 android on google.
If you want to keep your games running smooth specially 3d games like raging thunder 2, download memfree app from the market, this allows you to stop any apps running in the background that you dont need to free up mem for running the games better makes a big difference at times.
Will let you know if I find others

Also forgot to say there are some other great games dont think can play or see them on the market until the 2.2 update, also Herocraft’s games look worthwhile checking out they have rts games too, need to look them up on google as I think can only get the games for android from their website not sure.
Didnt include gameloft games as 1. you have to navigate there awkward site to get most the games 2 it seems a lot of the games that are suppose to work dont 3 the games that do work and the only one thats available on the marketplace to try asphalt 5 is really unstable and freezes a lot as its not optimised for the snapdragon processor in the dell streak uses, so curently gameloft games are ones to avoid till they sort themselves out properly they are a waste of money. Anyway Raging thunder 2 is a better game than asphalt the way at the moment.
