If you want to keep raising your mage's Strength, its up to you!
Nothing would give me more pleasure than spending an entire weekend raising my mage's Strength.
Actually, my Mage right now has the most powerful standard melee attack of the entire party, thanks to using a staff which sacrifices magic power for pure physical damage :)
I'm on the fence with regard to buying this game - RPG Maker games (or games that look like them) have always been hit-and-miss for me. Gameplay and presentation are usually not good enough to serve as the main reason for playing these games, and story, writing, and dialogue can range from brilliant and original all the way down to horribly bad ...
The writing is pretty good and funny. There are also tons of in-jokes from gaming ("Hey, Listen!"), and pop culture references. Reminds me a bit of Unepic, but significantly less juvenile. There are still some f-bombs present, so keep that in mind before you play it with your kids.
