OK, but modern RPG games like Mork Borg or Shadowdark can take 15 minutes to pick up, if you've ever played D&D.
I'm not talking about learning curve (in fact, learning curve isn't even a consideration for me, really), I'm talking about time actually spent playing. I have plenty of time to
learn new games, but only so much time to actually play (ie, "try") them.
I've literally been waiting about 14 years to get Mythras to the table. At the moment, my plan is to finally run Mythras Dark Sun when my current game wraps up (probably in 6 - 12 months). I also
really want to run The Enemy Within Campaign for WFRP. I have recently been looking into Planescape, and am really impressed with it as a setting. I have plans to run it using Worlds Without Number. I ran some A|State a
long time ago, but the campaign never went far, and I would like to get it back to the table properly, probably using Cities Without Number. I also have a Mythras Al Qadim conversion I'd like to try. The list goes on.
Mork Borg and Shadowdark would need to offer me a lot more than, "easy to pick up" to push any of those games back in my list. The fact is, neither do anything that particularly excites me, so it would be nonsensical to let them jump the queue over games that actually have me excited.
