My roomates and I were playing Zeus for a while, starting at Zeus 2.2. There are many things to figure out and many hidden gems that we discover every time we play. The biggest issue is that it crashes to the extent that it could be easily confused to be a feature and not a flaw. Pokemon are all legendary. The fights are very intense and they have very interesting stages, but the most confusing thing is the moveset. The way it seems is that some, maybe half, of the characters have TWO different Final Smashes, one executed on the ground and one in midair. The taunt buttons can execute special moves in some strange cases, like in midair with Metaknight. Some Final Smashes do weak damage, like Link's, some are instant kills no matter what, like Marth's, and some....some do nothing like Toon Link's. The entire game is one big puzzle leaving my friends and I with the following questions: 1. What are the moves? 2. Why does Samus's CSS portrait feature Squirtle? and 3. Sparkles???
Overall, it's definitely different in it's own regard and I see Zeus as different and separate from Minus and Project M, and it is definitely worth playing.
