The press and influencers have gotten review codes for the Cowabunga Collection. Reviews are glowing! Not just for the solid ports, but improvements made to the original games. Play the original NES game without slowdown and flicker! Play others in "god mode".
Each game features an INCREDIBLY well done strategy guide in the style of Nintendo Power, there is even a "watch" feature to watch someone expertly play the game...in which you can jump back in at any point and resume play!
For the super fans and collectors, there appears to be a TREASURE TROVE of material in terms of old concept work, style guides, printed ads (including private industry type stuff).
The only negatives I've seen come up are that TMNT4 isn't online enabled (the arcade version is), the comic and TV sections are just covers and stills (no complete comics or cartoon episodes at all), and all references to Pizza Hut have been pulled (which shouldn't be surprising).
I've got this on preorder. I'm not usually concerned about getting a physical copy of a game compilation...but this one seems ESPECIALLY well done and there seems to be a lot of excitement building for it.
