13" MBA w/4GB RAM and HD 4000 - ok for casual gaming?

[filmbuff]

I use my MBA for video editing and Flight Simulator X on Bootcamp. It is fine on medium settings which makes it more than enough for "casual gaming", whatever that is.

I have this exact model, and this should satisfy all but the most hardcore gamers. Here are the games I have on it so far, they can all run on high settings with solid framerates:

Diablo 3
Mafia 2
Batman: Arkham Asylum
Bastion
Pinball HD
Tomb Raider: Underworld
Machinarium
Back to the Future (Telltale Games)
Limbo
Zumas Revenge
Peggle
Minecraft
Rome: Total War
Sid Mierers Pirates
Portal 3
Borderlands
Grand Theft Auto Collection
Team Fortress 2
Left For Dead
The Sims 2


If that's not enough to fulfill your gaming needs, I don't know what to tell you!
