Vindictus

you need at least 512 mb of ram to run it.(minimun)
Even if you did get enough ram, there are other things that might prevent you from playing.

Vindictus (shows you min and recommended specs)

Can You Run It? (shows min and recommended specs, also shows if your computer can run it or not, plus solutions to upgrade)

The rating is based on personal opinion and experience. ATM i would suggest SC2, Atlantica Online(currently playing) or go old school and play Breath Of Fire 1,2 or 3 but skip 4 and if you play 5 don't even talk to me again.

Only game i ever voted as a 10 was one i made so i was a little bias XD I have never met a game that completely satisfied me.
