This game will be very very good mark my words. Personally, I would consider this game to be on the same par as BioShock or Mass Effect simply due to what I have seen and read about this game.
My problem is too many gamers are looking at this thinking it will be God of War for the 360 or the next Devil May Cry. This are wrong impressions as this game is an Action RPG more then anything else.
If this game is looked at in the correct light I have a hard time seeing it be subpar. Personally, I was a huge diablo fan and having seen several videos and previews of Too Human reminds me of diablo.
I recommend that you look into this further prior to judging the game. Better yet, wait for the demo which will probably be released in the next couple of months.
