Playing games from windows

Playing games from windows

I need to ask you a question . First of all sorry for my poor english ,
please try to understand me and if you post an answer please don't use
"rare words" .
I use Ubuntu 12.04 . Before that I used Windows 7 . I have changed nothing
from the hardware since I upgraded to Ubuntu . The games that I could play
before , can I play them now ? I only care about singleplayer mode so
anything like "Steam" or "garena" or any other service like this , it is
useless FOR ME
for example : I used to play AC3 . Can I play it again through wine ?
Sorry again for the poor english , and thanks :D
