Plague Inc. Evolved. Basically an enhanced version of the mobile game. Still in early access according to Steam.

One of the games I bought during the Steam Summer Sale was Plague Inc. Evolved. Who knew destroying humanity with a plague was so fun?

Borderlands 2

Probably Halo 3 since that's the only one from the main series I have never played.

Never really got into the PSP. Only have 6 games on it. Too many bad ports of games that were released on other consoles and not enough good exclusives.
