The game plays well enough and is a reasonably fun ARPG. I was lukewarm while I was dozing through the tutorial mission, but once I got to the first open zone, Hell's Kitchen, I was pretty happy with the game. There are lots of mini-missions, events, side maps and bosses to keep you occupied. If you like Diablo II, or Torchlight, and you can stand running around with a dozen Iron Men named lickIt, and born2pwn, you should give it a shot when it releases.
Marvel Heroes was fun enough, but it isn't really my kind of game and so I spent a few hours searching for something else upon which to waste my time. And though I am not in need of any new games (my current back catalog of PS2 JRPGs alone would last me until my death), I just can't help giving Valve more of my money.
And because I have a lifetime account and little self-respect, I found myself coming back to an old standby, Champions Online. CO is my go-to superhero MMO since City of Heroes folded. It is much-improved from its release in 2009. Pretty much everything from the gear, to the power sets, to the leveling has been made much better and CO is probably the best it has ever been.
I hope that isn't the case because I have remade my first and favorite City of Heroes character in Champs Online. Monochrome Girl is now officially a refugee from Paragon City. Hopefully, she will have a few more years in her new home before they shut down the servers for Neverwinter Online 2: The Drizzt Files.
