Team Fortress 2 is the most culturally influential game Valve has and possibly will ever release, period. All the playable characters have established themselves as household names in the gaming industry; and while the game may not be as big and cherished in the mainstream nowadays, it is most certainly super impressive how it has withstood with hardly any scratches for almost 13 years.

Although it is very popular and influential, this does not necessarily mean the game itself is as good as the legacy it set. It has a fair amount of issues that especially throw off new players, which doesn't help when a lot of the veterans are also jumping to other games. A lot of these are issues that could easily be solved if Valve cared enough about the game to properly update it and freshen it up.
