It's a solid ARPG for $20.
Most leveling builds are pretty straight forward; pick a skill theme and run with it. Around level 30 you'll start getting a lot of Uniques which you can extract and plop onto other gear as you see fit, ideally grabbing traits which leverage the skills you already use.
Endgame is a bit of joke, but the journey there is a lot of fun. I got to level 100 with my landslide Druid and got my glyphs up to level 15 by running nightmare vaults. Never beat a level >90 nightmare dungeon nor killed Uber Lilith, but I play solo and the amount of farming I'd need to mess with to not get one shot there was just too much lmao. Beat a bunch of 80-89 NMDs and had Duriel on farm (not that he ever dropped good stuff...)

Just know, to me, you're better late than never again.
