Even at $10 I would honestly not recommend it. They will probably pull a FFVRemake and release Next-gen version with +content so it would be better to just wait to see if they actually fix the game with the next gen version.
don't know what performance is like on the consoles but for $10 it's definitely worth picking up. the game has flaws and it's not what was marketed but it's not really that bad a game as some people enjoy making it out to be. i think it's worth more than $10. maybe $25-30. not full price though.
