ok, it's a browser based PHP game, it's initial round was based on PA (Planetarion) and has since evolved.
What makes DarkBattle better then PA is taht it's still a free game, and will always stay free. it's a rather fun game, tick based (1 tick = 30 min) and each round consists of 3000 "proper" ticks, and then a week (336 ticks) of Havok, which is where we get insane amounts of free resources to buy ships like crazy and attack who ever, when ever and where ever.
check it out, if you don't like it then there's nothing to do about it, but if you do like it, well hooray for that!
