6.5 isn't a bad score, it just isn't perfect.
tri-Ace has made some high quality games, but you have to keep in mind that IU was made by the same team that made Radiata Stories, which, I'll grant, isn't a great game, but it isn't bad either.
I'm picking this game up regardless of review scores, just because it's tri-Ace.
We'll miss you George.
