Tekkit is iirc bukkit based, the mods are all ported by the guys at mcportcentral.co.za which is half the reason people hate it
Also heedicalking is more or less right but is still missing the point: Minecraft isn't really about the vanilla singleplayer experience anymore for the vast majority of players, hence the move to multiplayer only (allowing them to focus on the multiplayer codebase more and allowing modders to also only support one platform)
Bad players are going to be bad players, patching their exploits is honestly a waste of time because they will find more. Blockland is locked down pretty loving tightly which is the only reason stuff is actually hard to exploit, that and compared to the people in the Minecraft community the people who work on mods here are practically handicapped (case in point: heedicalking). Blockland modding is more accessible and harder to exploit but as a result is also about fifty metric forgettons more restricted in terms of the functionality that's actually available to us.
The game is best when played with friends on a server that is fairly local to you. At lower latencies it's not a significant issue to play the game - it just gets worse a lot faster as latency increases compared to how Torque handles it.
Also combat should be a focus of the game, as environmental threats are basically null and void. The survival aspect of the game comes from surviving the waves of mobs, and honestly in open ground they're objectively not a threat at all. Without high latency you can survive a night fighting with your bare hands and no armor.
