Classic Command and Conquer with overhauled UI, rebalanced gameplay, replays and observer mode.
Pro Fosters creativity
Features an in-game map editor and is geared towards modding.
Pro Runs well even on weaker hardware
Pro Engaging and motivated community
Teeworlds' one-of-a-kind community is the thing keeping the game alive. Be it the community servers or maps or all the other innovative content.
Pro Easy to pick up but hard to master
You will never stop learning new tricks while playing Teeworlds, no matter how long you play. At the same time it's easy for new players to just pick it up and have a blast.
Pro Available from Steam and in Linux distributions
So it's easy to play cross-platform with friends.
Pro Tons of mods and maps
Pro Very fun and engaging gameplay
Even at relatively low skill levels the game is a lot of fun - think Worms in Realtime! The antics you can get up to while "hooking" yourself around maps is just silly :P.
Pro Very pretty
Pro Very intuitive

Pro Usually populated servers
Cons
Con In a grey zone
(The C&C guys are actually well aware of this project and are fine with it... so this isn't true.)
All CnC assets are still copyrighted by Westwood/EA and not freely available anymore, so per law, it is illegal to share them as mods. Also, Dune was never available as free download, which makes the whole mod illegal as well.
Con Written in C#, gets pretty slow with bigger map
Con Weird net-code
Even though the game is playable without issues and characters move like they should, they don't register enemies' mouse movements really well. Because of that, it's hard to tell apart who is a spinbotter and who's a legit pro player.
