They lost me a few weeks into CoD2. The console-ized crap-fest was the end for me. I had made a ton of mods from "Medal of Honor: Spearhead" then into CoD1 and the biggest projects were for "United Offensive". I was the first guy, along with a great community at After-Hourz.com to do Base Assault maps, "Berezina" anyone? And we did nearly 20 vehicles and AT guns etc. Oh... "Gun Assault"?? Anyone recall that map? A cult classic. But CoD2 just killed it for me.
I moved on to "Red Orchestra" shortly and we did a massive amount of map and vehicle development there, much of which you can still the see in "Heroes of Stalingrad" and the "Rising Storm" project, where I was on the initial team as Mapping Lead. Imo, the best WW2 game for teamwork and community content.
Anyway, haven't played CoD in years but if it comes back to being PC-like as it was, which is doubtful, I might look at it. Oh, the glory days!!!
