Before I first played FFX it really wasn't to my liking with the plot, atmosphere and characters but I took a shot at it cause after loving one FF game to the next...(ie FF7 then 8, then 9) I had to give it a try and I was glad I did. The battle system is fantastic and it was an overall fantastic game you'd expect out of a FF game really. You should definitely give this a try and these days you find the FFX collection to be pretty cheap so you dont have much to lose I feel. Once you put in a decent chunk of time investing into the game I'm sure you'll really start to enjoy it.
Interesting so you were in the same situation as i am now.. and yes you are right i can buy it really cheap today and don't have much to lose but i know the game is very long and i HATEEEE when i waste my money on a game and it wasn't worth it. It doesn't happen very often cause i'm very careful and i do research a lot but it happens sometimes so that's why i'm hesitating with this game.
