Red Faction...
I'm probably about a third of the way through the game and it just might be a top 5 of all time for me.
Had to rescue someone from a building and the ladder was blown off, so I took it slow and used my sledgehammer to smash pieces of the building until the 2nd floor was at ground level.. great stuff!
I can knock out a few hours in what seems like only a short time.
If you like games where things constantly blow up all around you.. at least give the demo a try.
