Thinking of getting into one of them.

played idle heroes for a few months. very fun game if you like games that auto-battle. i hit a wall after playing for a bit and game definitely slowed down alot. lots of things to do but got too slow for me. i am playing kings raid now.

I'd play bit heroes as auto is more so used to clear old content for loot, you will manual pvp/ trials/ ect. Has a decent amount of itemization but pet/accessories are random boxes from the gem shop, typical money sink (sunk 600$) getting my legs, some get it much faster and others sink even more. Tone threw 1000$ at one pet lololol (quimby).

Honestly don't play either tbh if you aren't invested.
