>>1475134Souls games have tons of shit to collect from weapons, armors, consumables, rare drops for upgrades and such. I just platinum'd demon's souls today and spent a good long while grinding the shit out of one enemy to get a single drop.
Final Fantasy and Dragon Quest have a bunch to collect, similar to Souls stuff. Although off the top of my head I don't know which one would have the *most* stuff to collect. Probably 12 and 11 respectively
BOTW/TOTK has a lot of stuff to find and collect. I think each item maxes out at 999 as well.
Kingdom Hearts is another game I think that has a lot of shit to collect, especially 2 IIRC.
The later Castlevania games have you collecting stuff, I can't recall if things stack but from SOTN onwards you spend a lot of time collecting items and weapons and such.
Dragon's Dogma has a ton of stuff to find and collect iirc.
Metal Gear Solid V, maybe?
The Tales series usually has tons of items and weapons to find and stuff like food for cooking so you can hoard all of that.
Persona and SMT has stuff to hoard too.
Sorry if this seems a bit disjointed, I was just rereading games I've finished and listed them off one by one.
