I think that's the 3rd comment for Tactics Ogre - looks like I might have to lose another £4 ;)
Cheers op. Hadn't even realised tactics ogre was on the useless vita store (y)
I know if's been cheaper, but to be fair it's only £6.99. Not an entirely unreasonable price!
Definitely get 4 - it was my entry into the series and still remains an all time classic. Ultimate Phoenix (Spoony bard that he is) is absolutely right about the music too!
I'd say go with 4, probably alot similar to others you played, might buy that one myself! Good battle music too!!
