Please note that I'm not trying to change your mind/opinion/feelings about the new Edge stuff. Just voicing my feelings about it.
The new, highly abstracted edge mechanic means it's all about how to game the system to cough up edge.
The avoiding a negative penalty here and finding a positive bonus there is all about how to game the system to cough up enough points to increase successes.
That works great for boardgames and the like where the abstraction is built in, but not for RPGs where reality trumps cool.
With the new edge mechanic srun is now entirely within the Pink Mohawk school of play, which is fine for many folks but flies completely in the face of my table's interests and indeed the history of srun.
While, I can see where you're coming from, we've obviously been playing with different groups! lol. Many times I've seen games come to a screeching halt as players hunt for every bonus they can get even if the end results isn't "realistic." It's STILL bonus hunting.
Plus, I wouldn't place srun in the same pool as Realistic RPGs. It's super fun, no doubt. But once a Street Sam starts running around like the Flash on Meth while the Elf Mage is lobbing fireballs at a Dragon's Lair Guards, ... er... Yeah. I'm no longer getting realistic. It's definitely on the Science Fantasy end of the spectrum.
However, I will concede that it IS possible to play it more realistically, but outta the box, it ain't. Squinting, I can see where the new edge thing may make that harder. I'll reserve judgement until I see the actual rules.
