well i just got back for OES IV and i had a pretty good time. mark is a super nice, laid back guy. he tries really hard to run a good, fun, game for his players and deserves a lot of respect for it. the ref in play system seems to work pretty well with the few minor exceptions but that's expected with anything. the game is run a little more like a big game than a true mission based scenario game. this leads to a less structured, more free flowing game. the actual playing field is still a bit rough. from what i'm told mark only runs a few games a year, and you can kinda tell that it's not a full time, professional field. i'm not trying to say that mark isn't a professional guy, it's just that you can tell that the field still needs work. pretty much everything is uphill all the time.(at least it seems) there are well worn trails that lead through to just about everything but no real clearings anywhere except for the main areas. the woods are pretty thick and a little difficult to traverse. i found the reinsertion a little frustrating at times as it's constant and people take advantage of it. the only real problem i saw all weekend was the air station. as much as i hate to say it, it was down right bad. their compressor never filled all the way to 4500 psi and i talked with a kid and his father that had gone to get their HPA tanks filled and they were filled with co2, ruining the tank. that is just really an unacceptable mistake. if they got someone new to do the air fills and some how made their little piece of earth more flat this filed would be really close to being absolutely great. i did have a good time and i will most likely be back at some point in time. if you live in the area, i think you should really support mark and his product.
