I really enjoyed the first two games and I really like all the added mechanics they put in to make it different but there are quite a few Quality of Life updates I'd say you should wait for until you buy the game. First being a restock of the town merchant and books. I would also have liked to see the lvl of enemies I'm fighting while in battle easier, I didn't like having to hover over each enemy to see what lvl they were at so I could set my battle strategy. The game says it will give you more tutorial as you go on but it doesn't. I found I had to figure out everything after the initial tutorial for myself, which means I was missing out on some game mechanics. I do miss the adding enemies for the first two games as you saw how much stronger you got when adding two guys made it hard but then coming back after a few lvls showed that it's now easy. Another issue I noticed material quests. It shows you have to go to a certain location but when I go there, the enemy I need is not there at all. So I went to another location and there would be one enemy I needed.
So a few Quality of Life ideas I think would be nice. I will come back to the game after a few updates as I figured it wasn't where it should be on release.
