If you haven't played the original I see very little reason to not just play that instead. It's cheaper, runs much much better and there's shockingly little in the sequel that really is noticeably different or improved upon. I've played like 15 hours of Dragons Dogma 2 and genuinely regret the money I spent on it.
Dragons Dogma 1 was cool in 2012 when there was basically no other open-world-rpg with decent combat, but in a world where Elden Ring and its DLC exists, Dragons Dogma feels ridiculously behind the times.
