IMO TW multiplayer is one of the worst mp experiences you can have, but why do I play it religiously? There are the immature people but you just have to ignore them. You will find them anywhere. You can, though, find people who are very nice and fun to play with. Just like rl, when interacting with people there are jerks and there are very nice people, and if you take the time you will find the people that are genuinely fun to play with and talk to.

My advice is if you want to play a fun game, create a game on a map that you want. Generally competetive people avoid anything that is not flat, so you wont have to worry about jerk-skilled people owning you too hard.

Another suggestion is try entering a clan game and just be very pleasant and talkative to them. Whenever somebody comes into my games and is acting very nice and happy, I give them tips and help them. Sometimes when I find people like this I usually play 2-3 games with them. When I am not playing against other clan people I usually just experiment and have fun, alot of people are like this. Learn who are the respectful clans who are good natured (check the nominations for most honourable clans and this will give you a good shortlist) and I can guarantee that they will be good natured to you.

No clan community? Well you wont really find one unless you look for it. CA isnt exactly promoting the MP community and there isnt really one that exists here on the .ORG, but a few of us are working on that. You cant go into the lobby without seeing a horde of clans, so I dont know how that comment can be justified.

As merc and bed have said, playing against people is so much more exhilerating that playing AI. Now when I go into SP I quickly become bored and dont really find it enjoyable. Playing real people is the way to go, and ever since I joined a clan about 2-3? years ago I have been playing MP ever since. There is a great community out there you just have to find the people you want to converse with. It is a choice, after a while you just ignore the lobby chat altogether.
