Look through the General Exit Path Discussion thread around the time EP2 came out. As I recall it's because he said he would put in a lot of cool new things, but didn't deliver.
ok, so, one of the first things is that exit path 2 does not save your stats, which is probably the most popular problem with it, plus i just get sooooo feddup with those **** sliding pole thingies, and lastly exit path 1 has lots of cool players in it, like kriss kahn, greenbox something or other..., and players who give out authorization (yck). And are you all ready for the worst reason why exit path 2 is way worse than exit path 2.....ok..here goes...EXIT PATH 2 DOES NOT HAVE DOUBLE JUMP OFF BLOCKS. The exit path 2 is when you can just tap the up button 2 times in the air for another jump, how gay is that!!!
