Back when GGPO had first started I was on there quite a bit.
I stopped playing XboxLive/GGPO for several reasons. The main reason was because the DSL lines in my area are crap. They went from bad to worse over time and AT&T did nothing to fix my issues. So I dropped them. Comcast in my area really sucks too, so I am stuck without a good quality ISP for now.
The other reason I quit playing HDR on XboxLive was because my offline game was really starting to suffer. Especially when playing ST on a cabinet. So it became apparent to me that I was just going to have to choose which one I was gonna stick to and which one I was just going to play as a novelty. I chose ST over HDR. Don’t get me wrong, I think HDR is exciting to watch and I am sure everyone has their reasons for loving it, but I had to make a decision. Some players have no problem hopping from one game to another, but apparently I do.
Once I have a decent ISP again I will definitely be back on GGPO
