I'm not sure how the rugby dollars system works. You seem to get $500 a game, whether it's a win/loss on any difficulty.
I like the game. Online it's a bit annoying, though it doesn't seem to play any differently (like fifa plays different online) as it seems to be set on hard mode, so conversions, scrums, lineouts and rucking all seem like they are too hard to contest at times. Also, i'm not sure why but you can't select the kit for your team, and twice i had the opponent have the same colour kit as me.. its almost like it picks the nearest team colours, as well as selecting a ref in that colour too.
I do love the glory cam, that's great, the lineouts are not repetitive, scrums are good (but seem to be on roller skates, can that be adjusted by stats?) and the mechanics of the game are good. It's just there is no tactical element, so you can't force a penalty at the scrum, or get an edge at the breakdown etc, by fetching the ball, for example. Dropgoals are horrible though.
I'm impressed by the free flowing nature of the game, and the editability of the game too. There's just a couple of pieces missing, and it'd be a truly great game if they were in place.
I'm not sure if these things can be modded on PC, but i assume there is some way to alter parameters etc.
