Not to say that the experience hasn't been all around fantastic, I couldn't really ask for a better environment for me to be creative and assertive, but at the same time here I go. The only run that has presented any real challenge hads been the scramble, which doesn't really include much random but includes a LOT of decision theory, which just isn't quite the same.
I recognize that designing a scenario for a completely unknown group of protagonists is a challenge that swings very quickly from underwhelming to impossible, but my voodoo touch mage has yet to face a serious challenge and has gained what I'll describe as a "ton" of karma for 3 days of gaming (9 runs, 7 and change karma each). The advancement has been awesome and tons of fun, but the challenge has been mostly created by having a built in negative synbiosis with nojose's character and occasionally being the antagonistic foil for the group.
A more experienced player had suggested at the most recent table that we increse the table rating from what3ever it normally is to 4. For saqke of time we couldn't do that on the fly, but the run was something of a gimme. Lots of fu8n and rewarding, but missing that integral challenge element, (already spoke with the GM about it, would talk to9 Bull about it but he'll almost certainly read it here).
Again, tons of fun, but not terribly challenging. With any luck and personla initiative we'll bring some con play back to the Milwaukee area soon, but it would be really nice to have some sort of enhanced challenge rating for players that have Tony Hawked the system a little bit. Nojose and I combine to form something of a Pun-pun.
