I was thinking of starting a campaign in 5150 No Limits but using the 5150 PI investigation rules. I'm thinking the only real things I would change are:
Firstly I'm going to shoehorn the transit system in 5150 Urban Renewal into the six areas in 5150 No Limits. This will done by generalizing locations: Space Port, Lower Hope (lower the 4 income areas), Pub and Rec, Middleton (middle income areas), Downtown (City Hall and Financial District), and The Heights. I believe there were 12 areas in the original transit system.
I'll simply cut the fitness score and use Rep if needed.
The weapons table could also be further customized by simply adding a few weapons from 5150 PI, namely the BAP (1 or 2 shots), the BAMP (1 to 3 shots), and the MP would just be a 3 shot weapon. This will give 4 different weapons (including the single shot pistol) for variety.
As for the races, I'm not sure but I plan on just having everyone Basic in my campaign so I'm not going to worry about it for now...Maybe a chance of robots! The setting will actually be Tokyo in the near future (too much anime!).
Any advice or input would be appreciated. I'm trying to keep it as simple as possible!
