This is what we are doing. Last years or so we've been trying out various TTRPGs, played them for a bit and couldn't settle on one we liked so we moved onto something else. It just became apparent that we were just more interested in hanging out as there was always a lot of distractions and side conversations, etc. Week before last we played our first game of the Arkham Horror board game. It was fun and while looking online for play walk throughs, I saw that EDGE Studio is in the process of releasing an Arkham Horror RPG, and they have already put out a starter set. It is a really well put together starter set. An adventure, premade PCs, and everything you need to play out of the box. It's designed to be learned as you play. There are little game rules, and no character creation rules. I'm just using the Arkham Horror board game/RPG as an example for
@Retreater but I'm sure there are other games that can do the same. I'm hoping that we can play the board game when we want a less immersive/complex game but then use the RPG when we want something of a more traditional roleplaying game. As they are both in the same setting the transition from one to the other should be pretty seamless in theory, a win-win for everyone.
