I don't think that there is much you can do about adobe. Even with the most updated version, some games simply won't run at all. As for games, it depends on your iBook specs. Halo for example reqiures an 800 MHz Processor, 256MB Ram, 32MB AGP GeForce2 MX or ATi 7500 (Or higher) and 10.2.8. You may be able to run Minecraft (In browser) if you have a very nice iBook. My 1.67GHz PBG4 usually plays that game at 30-60FPS. Other games you could probably play include Wolfenstein 3D, Call of Duty, Blood Rayne, Metal of Honor, and Tomb Raider, just to name a few.
