Well, with four people (three plus GM) it seems like we could get a decent game off the ground if we put a little thought into it. I've PMd everybody asking them to check into this thread if they're interested.
That just leaves the small matters of:
1 location
2 time
3 frequency
4 who's GM
5 rules
6 genre
For my part...
1. I'd be happy to host, or to travel elsewhere in the great metropolis that is Woking. I'm about 15 minutes walk east of Woking train station. Parking here is "interesting" at weekends, but easier in the week.
2. Any weekday evening except Wednesday, I'm free most Sundays, Saturday tends to be tricky.
3. How does "aim for every 2 weeks and slip when someone can't make it" sound?
4. I'd mildly prefer to play but I'm prepared to GM. If somebody actively wants to GM, don't let me stand in your way.
5. I'll play anything. I'd prefer T20 if GMing (since I know the ropes).
6. Let's wander around and have adventures. I'd rather avoid an all out military game or a hyper-precise spreadsheet-heavy merchant game. I like happy parties, of characters who actually belong together.
