Ehh, to a degree. Many of the default games are similar to the type that would come bundled with Windows 95. The better games need to be installed (as they would on Windows), and even then they're mostly just OK.
Robots is the only bundled Ubuntu game that really interests me. Chip's Challenge on Windows 95 rocked.
You had to install chips challenge. And there's always wine... but Ubuntu also has a "Chips Challenge Engine Emulator" that if you had the original copy of the game, you can play on Ubuntu too :)
