Fun and Simple Multiplayer Games

[Gwynplaine]

I'm looking for suggestions for some free or cheap games to play with other people over the web. I'm trying to keep the fun social aspect of gaming while having ditched that fatal first "M" in MMO. I know ZNES has a netplay feature which I've tried out a few times but apparently I'm too stupid to configure my router properly, so that's out.

Ideally games that are a little more nuanced than a lot of free flash junk, but any ideas welcome.

Gunbound can be what you are looking for~

You can play FFA or as a Team iirc.

It's a free online card game much like Magic the Gathering. 12 different elements, hundreds of different cards that you can mix and match to whatever kind of deck you want to play. Can play against different levels of AI or against people.

I think it's fun.

Altitude is a new and pretty fun 2d airplane multiplayer game available on steam for like 10 bucks, it's pretty fun for quick online matches and every plane is pretty balanced.
