It's the same with me. City of Heroes was my first and only MMO. Of course I try others over the years, but I always come back because this game was different. I had things here I have never seen anywhere else.
After my last crapy try with Guild Wars 2 (Friends play it, good reviews and so on but a boooring gameplay with doing the same things over and over again with absolutly no teamplay) I made the decision: Thats it. There will never be an MMO again like City of Heroes, only MMOs like Warcraft and this is not my type of game. Now I play other games I miss over the years and see what's happening with Matt Positron Miller and the others (My last hope) and the Plan Z project here (My very last hope)...
