Yeah, when I play a Call of Duty I am not really there for the good game design or revolutionary ideas. I am there to blow stuff up and shoot a lot of things :p I'll think about it, but very tempted

As for CoD1 and CoD2: They are still games about blowing stuff up and being a super soldier, but they were a lot less "team" oriented. So you still did almost everything yourself. And no CoD has yet to match the awesome that was Captain Foley's wild ride in the first CoD. Just be warned that CoD1 has medkits and that both games are a lot more unforgiving.
