Is that two questions?
Today I returned home but I have had only 1 hour of sleep so I can’t think clearly at this point. Therefore, I will be quick. Really quick.
The most complex RPG I have played is D&D 3.5. I had the chance to play it once and it was unnecessarily complex. As for the simplest RPG, I think I will go with D&D 4th edition. It blurred the lines between RPG and miniature wargame but, compared, to other editions it was pretty straightforward.
And I will stop here because I really need to get some sleep. Tomorrow’s question is “UNPLAYED RPG you own”. Oh, I have a bunch of them.
And until next time, have fun!
