Well I just came up here to ask about a specific setting, and what would be most appropriate for that setting, so I'll try appending to this thread looking for that advice.
I'm thinking about running a one shot starring a group from Bureau 13 (remember them?). I'm looking at high modern firepower (grenades, automatic weapons, LAW rockets, satchel charges, Urban Assault Vehicles, etc), magic (in setting and in characters), and more archaic weapons (swords, axes, cleaving, etc.).
The setting would be modern day (adding the magic). Since it's a one shot I'd like a system that will be easy for players to pick up (with preparation on my end of course, including pre-gen characters) and easy to run both high firepower and archaic combats.
D20 Modern lept to mind of course, but reading this it sounds like Spycraft 2 might fit the bill as well. I have really NO experience with either of those two settings.
Thanks for any recommendations!
