StarKnights is a unique strategy game in which you control an empire, playing against other peoples online in the pseudo real-time world. You can download it and play it right away, without registering! Registering unlocks your character's ability to move up to Level 4 - 10 (which is not easy to be achieved because of the experience points required..... I myself only has a (currently, on March,26th) Level-2 registered character).

The download is quite small for such a good game, though. It's only about 10MB. Worth trying.
