How does MH even work? You can solo small monsters but for the bigger ones, you have to team up?

The games vary in how they implement it, but this is basically how it goes. There are basically three ranks of monsters: low, high, and G-rank. Each rank provides you with better materials to make better gear. Depending on the game in question, the high/g-ranks will be unavailable until you play multiplayer or they will be available but the monsters are way too hard to solo until you get better gear. In some games you can have felynes join battle with you in single-player. Some games don't have G-rank at all, and you have to wait for the expansion. High rank monsters are faster, have more attack patterns, have more hp, hit harder, etc than low rank. G-rank monsters hit harder and so forth than high rank. Some monsters are only available in a certain rank, while others just get their stats boosted if you play them at a higher rank. The main goal of a quest is to usually kill a big monster, but there are variations on that. Some quests are just collecting materials. Basically monster hunter is a game for people who love grinding and the results grinding provides them. 

I am unsure how they are doing this in World since the game seems to allow any players to drop in whenever. 

Thanks for the heads up. I forgot this was going on this month.

oh boi oh boi i'm so excited.

(this game proves i'm a hypocrite graphics whore)

Oh so it starts tomorrow but you can download it now, that's fine I can wait another day.

Wait is the main game also online single player?

4-player co-op.

I should have clarified, is the main game going to make you go online to play the game. 

No idea. I imagine this beta is set up like this so they can monitor performance.
