Personaly, on 1vs1 playing, I'm against random effects. I played wargames soooo long that I don't want to use dices anymore in confrontations. I'm not saying it's good or bad, I just don't like it. IT's the same thing about TTQB, I prefer the sticks, not because they are better, but just for a matter of personal preference.
BUT random effects are a great way to improve solitaire game.
Like stadiums, and stuff like that.
To make a comparison, for me 1vs1 gaming is like playing pool, table soccer darts or whatever tabletop sport game. Solitaire game is more like roleplaying game.
