I've been playing this game since the first demo.
I would play it all the time with my brothers, whether we'd be playing through the game normally, fooling around with weird exploits/glitches, or downloading bizarre mods off the forums, we always had fun. I played it online for a time, but I almost always had a lot of lag and the community was kind of annoying, so I kinda stopped. I still play it offline a lot with my brothers.
This pretty much sums up what I had to say.
Though I play online more than any of us bro's, but I still find the community to be "meh" at the greatest. It'd be really nice if I actually had some friends to play with on there.
Though unlike 8BDM, I'm content in just playing it alone. 
The community over there is a little weird. Especially this one guy named Mystic. He is a jerk. But my friend from over there isn't so bad. Ofc I only know about SRB2 from him because he showed me in IRL. :P Him and I have been kinda working on a project for SRB2. I didn't know anything about dev with the Doom engines so I couldn't help very much, but since I'm hear at CutStuff I should hopefully start learning more about wad and map dev.
