I've been tempted to download it for awhile now, because it's free and looks pretty good. However, I heard it can get boring quickly. What do you have to say about the matter?
I downloaded Team Fortress 2 the day after it became f2p. I played earlier today. I've played over 221 hours of this game. I have not regretted a single minute. Download it now!
Go for it. The learning curve is quite steep and there are a lot of new weapons these days but that only makes it harder to get bored with the game. You can always find new things to learn and perfect. Definitely take some time to watch some tf2 videos and read the wiki first, the game can be pretty confusing. http://www.youtube.com/user/Niichts#p/u/0/nmUJkACaFSw http://www.youtube.com/user/Fatmop http://wiki.teamfortress.com/wiki/Main_Page
If tf2 is boring for you then you're probably not doing it right. There's always something new you can learn and have fun with in the game. For example, the latest thing I got into and I'm trying to get good at is Market Gardening. It's really satisfying too.
I did Play TF2 for a While, but It was foolish, i wasn't able to play it at my FPS, and I ended up being terrible.
I've gotten a lot better at it now, actually. I'm pretty good at using Medic and Heavy, and am alright with the Soldier, Pyro and Engineer.
