SST:LD was horrid, and I don't think it was based on space (can't remember, I deleted it fast), but on bugs or something. But all the models looked the same and the animations were rigid. Unfortunately, (IMO) GMD is suffering from similar things, rigid animations, similar models, etc. Other than that, it's not too bad, and there is a lot of units, but they can be hard to distinguish in the heat of a battle.
