A Linux who can play WIndows games is MandrivaPowerpack2008 commercial version of Linux with the CEDEGA program. Linux Mint has all other windows abilities except gaming as it is not programed with the gamer in mind,sorry
Just stick to Windows for games.
Actually i am with KiwiLinux a very much like Linuxmint but with the PPPOE ethernet protocol ,and is the only Linux to support my net connection. I am downloading a lot of software ,and i am happy when i see the menus full of games,Bitorrents downloads ,very advanced CD/DVD burning,copy and modifying ISO-s,a lot of music players,videoplayers , a lot of extensions for firefox, and a lot more. You will never regret a OS with full of software ,for your own pleasure ,at least i hope so
You can even see the Universe(some of it ) with Celestia emulator.It is very beatiful.
Of course you can have all this with Windows too,but with cracked applications ,because if you buy them one by one ,you do the accounting yourself, plus the cracked versions cost a lot of memory usage ,so i invite you in having your PC at top performance even it is not one of this kind.
I am telling just like OBAMA : WITH LINUX YOU CAN
