Last year, Madden on PSP was jerkier than Terrell Owens. It chugged and stammered like Warren Sapp. But that's all in the past. While the slowdown made last season's game a frustrating affair, 07 glides along smoother than the Bucs running back Cadillac Williams.
Of course, load times are always a factor in PSP games, but you'll go from Main Menu to coinflip in under 35 seconds. When you consider that each game lasts a full four quarters (and around 40 minutes if you're playing 5 minute quarters), that's beyond reasonable. For the minimal cost of only 9 minutes you'll have loaded up an entire regular season!
Madden's minigames are ideal for the PSP. You can dominate Rushing Attack while on a short subway ride, or topple Precision Passing on a long commute. But in direct opposition to the main game's speedy load times, the minigame loads will definitely test your patience. It takes around 30 seconds to get into any minigame, which is lengthy, but it gets worse if you're starting off a franchise.
There are 19 minigames in the franchise mode's Training Camp (more than on the PS2 or Xbox 360, in fact, which is a good thing), and each has the aforementioned long load in of 30 seconds (which is a bad thing), then a load out of around 20 seconds long. Add gameplay to that, and it's unlikely you'll get through the Training Camp and into your first season game, in one sitting. Which is pretty obnoxious.
