The big issue with Shadowrun, two really: they really messed up the game lore/history, and they dumbed down the mechanics. The game mechanics didn't need to be changed. They aren't that much easier, and in some ways are harder if you want to express more complex things, and they gained us nothing. Its almost like they just randomly changed things to justify a new release, rather than doing the hard work of actually improving upon SR3. To be fair, a lot of games lately seem to be dumbed down in their more recent versions. Its a sad trend to see. That said, I'd probably play SR4, but really hope to find an SR3 game, or a house-ruled SR4 that fixes the mechanics issues.
