Same-Scree/Multilayer games for TV at LAN Party

[Artificiary]

I'm throwing a Lan party soon and I'm thinking of setting up my HTPC with some games that people can hop on and play co-op or competitively when we take a break from the bigger group games. Ideally I'm thinking of games that can be played with a controller (I have plenty of Xbox 360 controllers and a wireless hub).

I have a few ideas already but would like to get some more suggestions from the [H].

List so far:

- Mortal Kombat Komplete Edition
- Trine 1/2
- Beat Hazard Ultra
- Forced
- Laura Croft and the Guardian of Light
- Magicka
- Sonic All-Stars Racing Transformed

Nidhogg
Samurai Gunn
TowerFall Ascension
STARWHAL: Just The Tip
Speedrunners
Gang Beasts
Crawl

Those are a few I can think of.
