The tekkit alliance runs on tekkit classic from the good old days. On the server you can enjoy wrecking your friends with red matter battles and nano sword duels or If you are looking for some more relaxed game play then try automating every thing minecraft with buildcraft and industrial craft then you can sit and marvel at your creation (when you aren't fixing it). The server runs factions and has a chest shop at spawn. All prices are based on emc. On the servers website you can join discussions about the plugins you think the server should run and any items and rules you think need enforcing.
