GMod Tower is a project comprised of many different unique gamemodes hoping to build a diverse community. Essentially, the server (or tower) acts as a base for all the gamemodes it contains. You are not limited to one type of gameplay. The community forms what makes the tower interesting and the community controls how it's ran. In the tower, you will have access to personal suites, stores, a whole batch of unique gamemodes, and much more. There are plenty of well-thoughtout features/systems for your connivence. Trading (including currency exchange), grouping, gamemode queuing, awards (similar to achievements), and hand-picked administrators, just to name a few.
It needs work to say the least especially concerning the lag if you are in different country makes it impossible to do many things because of the lag (try playing tetris with 200+ ping) also if admins exist they are ******* useless 4/5 times when the server is pretty populated and you walk in the theater theres either graphic animal castration videos or some other disgusting video.. you cant vote the vid off because usually the trolls gather there in more numbers than there are people voting it off
