I think starting out at level 1 would be alright if not for the fact that the game spans only ten levels. BG3 has a level cap of 10 which seems really dull. That shit was alright back in BG1 where the whole concept of a game like that was an all-new thing, but in this day and age, having the (supposedly) definitive 5e video game end at level 10 is disappointing.
Its an odd decision, Id love to hear their thoughts on it. WotC did a survey and pulled data from D&D beyond and stuff and the average player gets to level 6 before making a new one.its like less than 20% of players get beyond level 9. Might be even less than that. Long campaigns are hard to do. I mean *buffs knuckles* I am DMing 3 10+ campaigns spanning years but whatever. NORMAL people dont get to do it often. Getting to 15+ is the frigging DREAM. To have a game that is flat out saying its a solo D&D game, huzzahs for all of the people who cant get group together, and not let you get big is such a bizarre choice to say "this is not only the best way to do it, its the right way to do it."
