Just don't fall into the Sunk Cost Fallacy. The fact that these things have been expended should not be the driving reason to continue, in other words. I think all of us here have fallen into that before.It's that my dm and I have put a lot of time and resources into it (books, minis, etc.), and other player has, too
Probably. And not just because of the D&D game. X is a friend of yours. Friends should talk things out so that these things that irritate you don't grow and fester and ruin a friendship.I think I need to resolve my o own problems with X
I've actually played quite a bit of D&D 1-on-1 because for a while my wife and I were moving around a lot for a while. It can be quite fun, and it was a good learning experience for both of us.Suggestion: The new D&D Essentials Kit has some guidelines on playing one-on-one, i.e., one player and one DM. Maybe you and the DM could try that, if you want to keep playing in this world you've been working on?
