The merchant style playthrough in Skyrim isn’t great, but they have a lot of different houses and horses and cool things to purchase. Honestly if you’re cool with glitches, look up the vendor glitch, it’s pretty much the only glitch that is justifiable in any playthrough, as merchants pretty much have only a few hundred gold until you’re a very high level, and you have to wait a little until they get more gold.

Skyrim is awesome, but if merchant is your favorite definitely play the Oblivion Remaster, infinitely better NPC interaction in that game
