Mana, hands down!
I know for some reason it isn't quite as popular but Secret of Evermore is such a thrill as well. The same amazing battle dynamics and mechanics that just were so much fun to learn and perfect.
First game music project of Jeremy Soule as well, who has since become the most sought after music game composer in the entire industry.
Maybe it's nostalgia, but to anyone who loved mana and wants to relive the feel of the gaming experience I can totally recommend Evermore.
never head of that but thanks for that. I'll give it a look!
