The game is alright and I like that there's a lot to do and explore. I also liked finding all the items and combining them to make the endgame super weapons and accessories, even though it was tedious. But I have a lot of problems with this game which pretty much ruin the game for me.

-First off, the inventory/chest management is super annoying and is a lot of work
-I also hated the fact that you have to make arenas for every single boss.
-Furthermore, the NPC happiness mechanic or NPC housing in general is a chore
-Potion ingredient farming is the lamest shit ever but almost mandatory on expert difficulty and higher
-Fishing sucks
-Early pre-HM is a boring slog especially for summoners and mages
-Early HM is brutal with the crazy increase in enemy difficulty relative to your weapons/armor at the end of pre-HM
-Corruption/crimson spread in early HM also screws up everything like NPC homes and biomes if you didn't spend hours in pre-HM making hellevators etc. to contain it
-Also the ore progression in early HM is dumb. Pre-HM does that way better.
-Melee class is trash until they get access to weapons that allow them to attack at range which basically turns them into a ranged/magic class
-OST is terrible

Even with those problems I did have a great time when I first played this game on Classic mode. However, almost every time I tried to replay this game I would get frustrated with it and quit before finishing it, usually somewhere in the beginning of Hard Mode. Nevertheless, I did beat Expert Mode at one point.
