I don't understand dnd beyond playing BG games but I don't really get this criticism. BG 1 max level was 7-8 and it was fine
Was it? I remember playing it back then and feeling cheated. Dont get me wrong, I loved the story and game play but we didnt have the internet and communication we do today. 22 years ago, when I was 13, I still remember going into a game store (electronic boutique I think) to pick it up.
Quite a few of my friends who played D&D in after school clubs were discussing it and saying they wanted to be higher level. We got our wish exactly 2 years later (bg2).
Don't get me wrong, I am not saying that it will severely hamper the game if we dont get to levels 10+, I am just saying that I would LOVE to not have the same old tired progression I currently get with table top.
Lots of previous games have had little to no trouble implementing high levels, I cant see why BG3 cant do the same.
