After playing X-Men Legends, X-Men Legends 2, and Marvel Ultimate Alliance, this series is just done for me. It's all so tired and repetitive. Yes, I've gone through rooms and beaten up the same enemies over and over with various super heroes and villains before. None of it was really all that fun the first time. Even with multiple players, we still have to contend with the proper use of gear that we find, which is all very tedious. Hmm... should I equip Thor with Gear A, which raises his HP by 100 and Speed by 5, or Gear B, which raises his HP by 120 and Agility by 4? God, just make it an obvious choice. We don't find gear this confusing to equip in most console RPGs out there.
Once they polish the engine and introduce some imaginative level designs and enemies, then I'll think about getting back into the series.
