Dominique challenge takes 1 hour and 15 mins roughly but Dominique is a beast. You would have to pay 100K in the market for him and you get him for FREE.You can even use your starting line-up.

2 brothers is 12 minute quarters and crazy cheesy. Marathon is also 12 but I don't remember it being too difficult. Ronnie 2k is 6 minute quarters with a super stacked team versus three silvers I believe. Can't remember about the rest.

Definitely do the nique challenge though. He's really fun to use.

These two are 6 min quarters, you can beat them easily if you have good players.

I did the LD2K Lakers challenge today, won 126-123 with 12 minute quaters (12K MT).
You need at least 8 Celtics including Historics. Was a fun challenge but Kobe had some BS shots go in even with Dennis Johnson having a hand in his face.

I got absolutely crushed by that 2 brothers challenge last night I think. Was my worst beating ever. Started out ok. In the first quarter I ended up by 1, was shooting 58%, they shot 52%. I think by the end of the game though they were shooting 62% or more and my head was spinning. Couldn't stop anything from going in and ended up shooting 38% for the game myself. It was bad.
