Suckers could have saved me $8! Oh well, at least with a rental I can play more than a demo. So far... I think the scores it has gotten are pretty accurate. The controls don't feel perfect. I haven't gotten too far in, but it kind of feels like Just Cause, but not as good. I expect more variety in missions in Mercenaries 2 than in Just Cause. There's only so many times I can take over the same damn village or meet with the same damn corrupt army officer.
The driving controls bug me... WTF @ using face buttons for gas/brake. Yeah there are weapons on some vehicles, but I'd still rather use the triggers to drive.
Just Cause 2, now that's a game that could be pretty sweet if they focus on improving the areas where Just Cause was lacking.
