It's not that terrible. One of my personal favorites actually. It has a lot of bugs, but it's nothing compared to AQWith in terms of bugs.
1. SS2D uses Hidden Project files. (Leeching from AQW? Ok. Leeching from other Private Servers? Nonono.)
2. Never heard of AQWith, must be also a bad game.
3. Also, the guy that posted this sucks. He is the most annoying guy I know.
Btw, check out Azerron. It is pretty undeveloped at this stage, but the staff actually develop the game and is NOT an AQW ripoff.
