I got... sort of blind-sided into running a GURPS campaign I was actually looking to participate in. While I'm thrilled at the proposition, I realize I'm in a bit of a bind and could use some advice. For anyone who has run GURPS before, especially modern or crime, are there any tips for keeping myself from getting bogged down with data? I know GURPS is designed to be rules-thick, but I want to find a way to tone down my all-or-nothing approach and keep the game running at a less-than-murky-sludge pace. Non-specific to a system, does anyone have some tips for a neophyte GM to keep sessions interesting and flowing? It's looking to be a bit of a sandbox campaign, with modern crime elements. Specific to Roll20, what can I do to ensure players are involved and active, so that the game doesn't sputter and stall for lack of involvement? Are there any networking tips you all might have? Any other thoughts would always be appreciated.
