Hmm, I was gonna say moonshades, last time I played it there wasn't much for things you could buy. But when I look now, there is. So I can't say for sure how unnecessary any of it would feel now, but it wasn't necessary back when I played last. It's kind of like the old early 3D party dungeon/maze crawlers where you use the arrow keys to walk one "block" at a time. There is only 2 party members in this. So you still sort of get the group synergy stuff, but each character is a bigger share of the team power. You could do a tank/healer thing or magic damage/melee damage, or not have either one focus on anything in particular.

I hope it's still not necessary to buy anything, it was a good game. But the store is pretty comprehensive now, so that has me worried.
