I have been playing MW4 ever since the beta came out around a month ago, and I still don't think I will be putting it down for a while. MW 4 has everything that MW 3 failed to offer.
While the AI has a few problems, and there is an occasional rough spot, the finished product is one of the most complete and compelling games we've played, and easily the best MechWarrior game in the series.
MechWarrior 4 has more types of BattleMechs, missions, and weapons than MechWarrior 3; the multiplayer competition is outstanding, the artificial intelligence is improved, and the graphics are generally splendid.
It's a fantastic introduction to the MechWarrior series for those who haven't yet discovered it, and it should have enough depth to keep veterans involved for a long time.
