Jumping off the topic of online play, can anybody recommend any mods? I've been wondering if I should download Tekkit, as it seems quite nifty, but I'd like to hear other people's experience with it first. It's been mentioned a bit here, so it seems like some of you might know stuff about it...
Are there many bugs? Having several independent mods thrown into one bucket seems like the recipe for conflicting code and such.
Is gameplay altered to a very big degree? For example, are any Vanilla Minecraft mechanics altered to the unrecognisable, or flat out deleted?
If I ever should uninstall it, can I go back to my "pre-Tekkit" worlds and play as if nothing had happened?
Anything else to take note of?
Any answers, or recommendations of other mods, would be appreciated. Thank you!
