MH is a franchise that takes a lot of time to get into. I recommend you watch a lot of videos before buying the game. Online is a very important aspect of the game but you can do all the missions offline so there's no big issues about it.
I heard that MH 3 Ultimate makes some things "easier" for new players, like having all weapons types at the beginning so you can choice your favorite very early and having a better starting armor.
I recommend you watch this video before making your decision, he's my fav reviewer and he makes some great points about the game.
