Free Games that Fit on A Flash Drive (Multiplayer Hopefully)

[brickybob]

My List so Far;
-Halo: Combat Evolved/Custom Edition
-RSBot 2 (I don't like Runescape's official client, too slow and RSBot JUST loads the game and not the ads.)

Need suggestions, my and my friend are going to have a LAN party. :D

We gotta know what size flash drive.

Because it could've been this.

Or maybe this.
