7.5 is almost spot-on, I guess. I would have go with a 7.
The things that bugged
me the most were:
1) The looping animations in the adventure dialogue sections. They also keep looping when the corresponding voice line has been played. I don't ask for a high-tech lip-sync, but...
2) The low-quality compression of the FMVs.
3) The lack of subtitles in many situations. Peeking (naughty-naughty) into the game directories I noticed that there are actually subtitles for those sentences which are not subtitled during the game (WARNING: there are also subtitles from the second part of the game, I guess). How come they were not implemented? A complete closed-captioning system makes the diffusion of the game easier, especially in those countries who don't understand English perfectly and lack powerful distributions (and translations). See Psychonauts.
4) Confused and unclear distribution. Lack of an authoritative reference-website.
