well to be honest it sounds like only the gamesradar reviewer and BIGBADBESTWICK have actually played this game. I personally also like this game so far. I would definately say the rating is probably appropriate and that the GR reviewer was honest, but more focused on praising the flaws. If you liked it before, TRY IT. I had never even heard of or seen this game before buying it. (was out of the mix and getting back into my xbox now that i have an hdtv :P)
If any downfalls to this game it is this, when i had bought it a week ago i had a 30" regular old tv. The words were hard to read in menus and anything outside of ingame communicating. And 2 days ago I bought a 32" samsung class c 720p hdtv and the game is alot better to see. But I had alot of issues reading prior to it.
I bought this game and then infinite discovery a day or so after. If you've been around the final fantasy series at all, it really isn't that complicated during battles. I do agree on the loading times BUT that is worth the sacrifice for what is a fun game.
