Since RotDG adds in more additional dungeon levels and bunch of new items as well, ideally the inventory size should increase as well since players need to carry around more found items, imo. It would be nice to have a second page in the inventory
I like this idea due to convenience, but keep in mind that a character seldom uses/needs items outside its classes/skills. I'm a melee character and do like to keep projectiles, but all but 2-3 wands are useless, same with thrown items and bolts and crafting tools. The bulk of my inventory is buff shrooms and potions. This leaves me with 1/2 my inventory free, when I want to be stocked up. I haven't used crafting skills much, so not sure how bad inventory space is with those. So after babbling this, yeah more inventory would be nice.
I support the idea, but then again, I don't know the items too well yet and probably keep some stuff that I don't need. Without any crafting skills, the inventory seems fine. I suppose that will change when I try crafting skills.
You don't necessarily pick up items and stock them up to be used in crafting though that's what most people collect loot items for. Like me, sometimes when I find valuable items though they won't be much of use to my classes, I'd still stock them up so I can resell them to the shop guy for money xD Yes you can sell items!
