Can try us out on Vegarlson asylum. We allow four boxing currently through Luclin, with future plans of releasing planes of power. We use the original bazaar and currently see anywhere between 2-10 traders actually selling items on a regular basis. We also have the original arena in, which i think is fun. Because we use the new client it allows us to use new npc models, so things like gorillas, wurms, spiders, and many more are all replaced all around the world with the most current models, and that actually ends up looking pretty darn cool in some places.
It is worth noting, the main difference between us, and a server like p99, is we run on a new client with current code. Content is tuned and tweaked to ensure a more classic experience, and undergoes fixes on nearly a daily basis, but because it does use the new client things will never be exactly as they were. Even on the new clients though, when you tune the content correctly, it brings the experience very close to where it should be. Still a lot of fun, with a really great player base and worth checking out!
