Darilon: Is it recommended to use TuTu or BGT over vanilla? I am not that far in yet so restarting is still an option. I started on vanilla mainly to play instantly but don't mind putting in some effort to get it going. I also bought Baldurs Gate 2 in the sale and have it installed so BGT is an option.
Absolutely, no shadow of a doubt, play it vanilla first. Why? Because if you go straight to the BG2 engine, you are not playing BG1 at all, you are playing BG1+ ... there are just too many differences and changes, and you will completely lose, forever, the unique BG1 experience. Play it at least once, beginning to end, as vanilla, and then think about having an enhanced experience with mods. Don't do it to yourself to go for the + version off bat... really.
