Did you like the humour of the first game? Or do you want a more serious story? I want to know your opinions. I wouldn't mind a serious story if it had some humorous parts or dialogue. And yes, I spelled humorous wrong.

I want it to be like the first one, serious with humourous parts; but it didn't take itself seriously and that was what made it funny. The first BC sometimes tried too hard, and some jokes were a little cheesey, but overall that was one awesome campaign.

Non-Serious. Stick with the formula.

I would like a mostly humorous story

I'd like humorous events and characters in a serious situation. 

I would like it to be serious but have some snappy one liners and humorous dialogue. 

I like the whole '3 Kings'/'Kelly's Heroes' bit. I'd like to see the story go a bit more serious. Really put the B-squad through hell. I doubt, that they will turn the B-Company soldiers into some kind super-serious 'Yes sir!' military elites. And that's a good thing.

Like the first one.  
 
Games don't often make me laugh, but the mission objective "Stop Haggard invading a neutral country.", whilst he runs off shouting 'There's gold in tham thar hills!', cracked me up.  
 
Speaking of funny games, Yusuf Amir in The Ballad of Gay Tony - which is great by the way, the best of the GTA4 stuff imo - is the funniest character the GTA franchise has ever had.  He's brilliantly acted and there is one Yusuf cutscene in particular that nearly had me in tears.

Lot's of love for Yusuf!
 
In real life I would be pissed at such a guy though.

whatever the first one was. it was great
