It's fun I'll admit but it's not a game that you'll spend a lot of time on
Gameplay: While the gameplay in Luminous Arc is somewhat the same as Tactics, it's just not the same. First of all, I feel like the characters can only move two or three steps. In other similar games, the characters feel like they can move much farther than the ones in this game. Another thing that I found disappointing was Witches/Archers. Their spells/arrows can only attack a few spaces and these are supposed to be characters that can attack from afar. I don't know if it's just the same but I feel like this game is a bit "slow". Also the lack of job changing is disappointing. The best thing about this game is the multiplayer. Playing on Wi-Fi is a blast and even playing locally with friends is fun. Story's not too bad but it could've been way better.
Graphics: Though the graphics in this game are already decent, I can't help but feel that it could've been better and cleaner. Spells/Skills look a bit dull as well. The different character sprites look alright though.
Sound: Sound's not too bad though the voices of the characters can get annoying after a while. The music is a bit dull as well but it's alright, it grows on you after a few battles. The music in the intro movie is awesome though.
To sum it up, Luminous Arc is a good game but I think you should rent it before buying it. It's not that it's bad, it just feels lacking. Multiplayer is really fun though but you need Wi-Fi to get the most out of this game.
