I just received my copy of the GTA4 DLC =) I added a copy of the newest Vagabond into my cart for free shipping. If you aren't into reading comics/books/manga than I would recommend EDF..
EDF! EDF! EDF!

It was repetitive, but when you play the harder difficulties it is never dull.

And playing co-op makes it even more. Planning precise strategies to win each phase in Inferno and dying 5 seconds after the phase starts makes all of it hilariously fun

Thanks guys. Will pick up the games and GTA4 expansion...

Try starting a new game on hardest with no upgrades, than tell me if the game is still dull when ants are able to 1-2 shot and your rocket launcher you start with is now a joke and requires around 10 shots to kill 1 ant. Of course I'd recommend finding a friend to help you. I played on hardest from the beggining with a friend and wasted a good 10 hours to get to mission 5. After we got homing missiles and a super powerful sniper it wasn't as bad but still damn hard ><

EDF is awesome. I liked it more than Gears.
