Me and my friend are going to choose a mod pack not knowing which one is best we want one with loads of players that regularly stay on the server. We want lots to do that will last us months, we want challenging things and easy things. We want to explore mine goto different worlds trade PVP.
there isnt much PVP but in terms of having to work for a long while, Infinity Expert. That will keep you busy for a long time.
This might help, it's from a different thread but I liked the response so copy and paste Civilization is probably best for what your looking for though.
