Marvel Crisis Protocol, Infinity by Corvus Belli, Frostgrave 2e, Relicblade, and going to be trying out the new 10th edition of 40k soon.
My most memorable would have to be the first Frostgrave 2e game I played with a buddy. We were using a custom board I built and plenty of beautiful terrain, both with fully painted warbands. We were both in it for some casual fun, as our normal wargame group had been nothing but semi-competitive Marvel Crisis Protocol for about two years. We played it for fun, narratively and casually, and both agree it was the best wargaming experience we'd had in a long time. In the end, it was pretty much a tie. I technically won, but when calculating XP gains and gold for the mission, the only difference was me coming out with 5xp more than him.
