Well I only did 1 full pt so far, soo don’t know if I’ll get bored the 2nd time, but I actually liked every next Act more than the previous, and Act 3 was the best for me. Despite hitting level cap like 1 hour after getting there with 50-60 hours to go, despite performance issues etc.
It’s REALLY good - it managed to keep me engaged, playing RPG without exp and without progressing the character for a good 1/3 of a game - can’t say I know any other RPG that can pull that off.
