Nice to see you here, [MENTION=90370]Zak S[/MENTION]. I've been a lurking fan of your website ever since you sent me a Google+ invite. I learned about LoTFP from you and purchased the pdf sometime back, too.
For me, I still like the Castles and Crusades system for 1e retro clones, and Dark Dungeons for when I want to get BECMI back and running. I also like Labyrinth Lord, however, and the Mutant Future rules that clone Gamma World.
[MENTION=6698278]Emerikol[/MENTION] , thanks for mentioning ACKS. I love the campaign level play from BECMI, so ACKS looks like something quite different while simultaneously right up my ally.
