Grinding is fun. Some classes and monsters have changed due to their sprites being replaced from a newer game. Not really a deal breaker for me. I think the newer sprites look nice. Another down side is the tsunami bomb track is replaced. Those are the 2 biggest downsides. There are a bunch of QoL improvements from the original including turning animations off and being able to stack 900 Statistician instead of just 300. Another HUGE time saver/QoL is that cave of ordeals 3 has higher level monsters in Etna Mode. With the strongest monsters bill passed, in etna mode, the CoO3 monsters are roughly level 4000. While having 900 Statisticians and a leveled cosmic sword, I was able to grind a reincarnated Divine Majin back to 9999 in probably less then 30 mins. I platinumed this game in 80 hours. It probably would have taken me like 300 hours if it was the ps2 version. Very based game. Most of the Disgaea games end up being pretty sappy and the characters can be very annoying but I like this one the best.
