I've got 5150: New Beginnings Urban Renewal and 5150: New Beginnings New Hope City PI as PDFs. IIRC I stopped playing them as you spent more time rolling o :on tables and less time playing with miniatures.
I remember reading the 5150 New Beginning rules a few years back, and yes there are LOTS of tables. However, I might still make it work for me if I pregenerate the encounter and feign surprise

.
Say, encounter Holdup of Pharmacy, X number of drug addicts, hostage situation. Do I need to call in SWAT team? Backup? Can my partner sneak up on them while I keep them talking?
If I know the scenario, circumstances, numbers of enemies etc and THEN set the game up I think it still would be very enjoyable.
