In that close up of the board it looks exactly like Risk to me. Like Monopoly, there are different sets or quality boards you can buy. Some had wood pieces, some plastic, some had numbered units others with horses and men like there. I think there the men are 1, the horse counts as 5 and the tank as 10.
The only thing that doesnt match is the dialoge. Reese said artillery materialized on his border when he went to the bathroom but there are no specifc artillery pieces in risk. Also I think Hal talked about Antarctica which is not on the map. There are other more complicated board war games then Risk with more intricate units. I think Malcolm was just being generic in terms of the plot.
I played Risk a lot as a teen. The clock stikeing midnight was not a barrier to starting a new game! Yes im a geek.
Puma clothes did seem to appear in the show alot. I wonder if it was just random or actually product placement? What is interesting is Puma sponsors Frankie's racing gear.
