Happy Wheels

I cant really think of other games.

Well you could go around the web and find some flash games. You could make a series with flash games. (Idea: FGF. Flash Game Friday)

Dungeon-Party

Wizardry Online

Mabinogi

ROSE Online

Dwarfs

Maple Story

Brawl Busters

Spiral Knights

Team Fortress 2

Each one are a selection I plan to go over at some point as well.

I run a small channel: https://www.youtube.com/user/SlotMagPro

Where we aim to play anything and everything we can acquire. Let me know on skype: foagal1775 if you are interested in joining or linking to us.

It's hard to start them free to play. You could do a popular game you already own. Minecraft Is always good, or happy wheels if your good at commentary. Dota 2

Realm of the mad god.....
