Well i personally wasnt a fan of X, way too linear for my liking, probably the most linear ff game that i can think of off the top of my head, not bad, just kinda limiting.
And i liked XII, ok yes there were the star wars comparisions all over the place, but it though it was a good game and while i can see why people dislike it, i dont see why its called the worst of the lot. Its probably the ff ive played the most besides 7, 8 and the original.
As for XIII, well i tend to hold this up as a prime example of games that take far too long getting started as dear lordi it took me hours to get through that opening section...
Oh and i wanted to shoot hope for been almost an emo parody.
But thats more disliking the team than the game.
As for X-2, for the life of me i cant see how anyone likes it, im not even sure where some of the stuff comes from, like paine, still have no idea where the fudge they picked her up from (can anyone enlighten me here?).
Also, i will admit, i never finished it as i got lost at one point, leveled up twice and found myself getting slaughtered by enemies, apparently by level 40 most enemies are harder than the final boss...
I know its one of the more popular of the series, but to me its badly designed (who has an rpg where your almost punished for leveling up), a story that was almost embaressing to listen to in parts and as a whole just seemed kinda pointless to me as i didnt think a whole lotreally happened, but as i said i only got close to the end, so stuff could go down right near the end for all i know. But i think the fact its the only main ff game ive never finished shows something, even if its only for me.
