the DF series is what i cut my online gaming teeth on. i still have them somewhere here.
I'm in the same boat. When I started off gaming, I had no idea what to do with all the extra team members you got with Rainbow Six games, and since Delta Force generally had solo missions, i just loved it!! Recently i decided to throw Operation Flashpoint back on my computer, though haven't had the opportunity to fire it up yet, think i'll include Delta Force on the old game revisied list. Hell, with RavenShield's age, it's getting close to being on the revised list. Especially with all the dissapointments we've had lately with UBI.
edit: Something i cannot wait to see is how these older games will look on a modern day rig, especially since I upgraded graphics cards in order to fall into the Vegas trap.
