Darkfall Online : I didn't read any specifications that the game had to be on any particular hardware.
Darkfall Online Description : New School Ultima Online basically. Full World PvP, Full Loot, Skill based, FPS/TPS, Have to aim spells/arrows/melee, Mounted combat, naval combat, Build a city or hamlet(small not well defended city), Battle dragons, Huge Seiges( 100v100 ), Siege weapons( cannons ) used to take over Cities, etc..
Only downside to this game is the other people that play it. You got the lowest of the low people, Non-stop Sh*t talking. Like everyone is 12 years old. However most over 18 I would bet.
Was a fun game for the first year. Then it kind of went down hill.. very stressful.
