At first I was hyped to have it, played it and didn't really get that into it until I nearly reached about half way, then I couldn't stop playing it. Since then I went back and replayed again and now I'm working on obtaining the SE and reaching 100%. I'm only on 86% at the moment though, so there's still a rather big chunk of work to do but I'm really enjoying it, it's different. And fun.
This game is the first to FINALLY be post KH2. Its impact on the big picture so far seems to be informing Mickey and thus Yen Sid about Sora's connections to TAV and Namine, Xion, Roxas and Axel being ones whose torments need to be lessened as well. As for whether or not Data Sora and Riku affect the real things, similarly to how the digital versions of HPO from KH2 affected their real selves, remains to be seen.
For some reason I just can't really get into Re:Coded. Maybe it is just that I haven't gotten far enough in the game to really enjoy it, but I have had almost no desire to play it. Probably should not have spoiled the ending.
