I picked up C&C3, and after only 2 moderately successful campaigns on the GDI side I'm already getting my sorry butt severely booted by the Brotherhood, and I'm playing on 'easy' mode. So I like playing games, but obviously that doesn't make me any good at them.
No messing about with the venerable RTS formula for C&C3. Establish (or rescue) a base of operations, fortify base defences while simultaneously building up a massive army comprising a variety of capabilities. When ready, send the troops over the hill to wipe the enemy off the map.
The game is graphically a treat with destructible terrain and firefights that are awesome to behold. When units gain access to beam weapons and railguns they light the map up in a breathtaking firestorm whenever they encounter their opponents. Such eye candy makes even losing a few units bearable while learning not to do "that" again.
Setting the battles in context are live-action cutscenes with a number of characters played by actors on the sci-fi circuit. Michael Ironside and Billy Dee Williams head up the GDI, while Joseph Kucan and BSG's Tricia Helfer lead the Brotherhood. Helfer's BSG compadre, Grace Park (whoohoo!), lends a supporting role -- now, there's a reason to get through a battle and open the next cutscene quickly!
This is a game more suited for multi-taskers. There are resources to balance and allocate, favourite units to keep an eye on, and battles to wage on a number of fronts. People like me who can only focus on one problem at a time frequently have their asses handed back to them on a plate. Never mind. If I can't multi-task, I can still exercise my persistence and resilience, and the payback they get when I finally succeed will be sweet.
