So I'm really interested in trying this mod, I beat the original one time (didn't really do any postgame content), and this looks really interesting. The trouble is that I feel I didn't really GET the whole system of the game even playing it all the way through, and any postgame or sidequest type stuff seemed WAY beyond my level, even after beating the final boss, and the tedious leveling required to approach those quests seemed so daunting that I eventually just canned it. Will I be able to play through this without getting too confused? It looks like all of the changes are for good so I'm hoping its simplified a bit for me, but wondering if maybe I should just grind my vanilla save to maybe get more informed on what the new changes in the mod are? Thanks for any input in advance
