Rollerball is a good action movie?
Well, I can't argue taste but if you think Rollerball is good then you probably haven't seen a lot of 'bruckheimer era' action movie you didn't like. Which isn't a bad thing if it keeps you from feeling cheated out of your money 1 time out of 2 when going to the movies.

As an amusing aside, on rottentomatoes, the first Rollerball has scored 80% of positive critics while the new one has 3%.
I love checking Rotten Tomatoes for movie reviews. I don't put much stock on
one critic opinion since my taste don't always fluctuate in the same directions as most, given my strong bias for the spy genre and for anything that has a sword in it. But if you gather the reviews of over 100 critics of different horizons and bias and the movie can't muster more than 30% of positive critics, there's something very wrong with it. 3% is abysmal. The number of movies that manage to score less than 10% is actually smaller than the number of movies above 90% (which does include action movies)! You have to do everything wrong (which that movie did, IMO) ; acting, scenario, directing, even the frigging the soundtrack.

Killing Glare is... not a very good avdenture. It is a essentially a contrived excuse to get players on a brawl site and use DMZ rule.
Urban Brawl is detailed in Shadowbeat, p.68.
