The whole connectivity thing has got to be the worst good idea ever. It seems like no one reilizes just WHAT you can do...
Suppose sony releases Champions of Norrath 3 and a PSP game. Through connectivity, one could transport their character between the PS2 game and the PSP game. This way, you can take your brand new, lvl 3 Ranger with you to work, and lvl up a bit on the ride. At that point you can return home, reupload the improved ranger and finally get past that damn dungeon.
Imagine 4 friends who play online together and are completely glued to their screens, trying to beat their friends: they can all take their Heroes on the go and it will only cost them the price of another game.
Sonic Adventure 2: Battle for the gamecube has a similar feature to that. but it simply featured chaos! Sure, they're pretty cool but it doesnt have anything to do with the main game!
The possibilites for on-the-go-gaming are endless:
--A third person shooter where the player can buy new weapons/skins, and getting the PSP version will allow them to make money anywhere they go
--The everquest fan who actually has a social life can lvl up their character on the go in a type of 1-player mode: no items, no friends, just training
--The Midway Arcade Treasures freak can play their favorite classics on the go and upload their high scores, via the PS2 network adapter, to a table online, where they can see just how bad they really are.
--Make a small game using a PS2 "game maker" program and upload it to the PSP. Yeah, thats a little too out-of-the-box, but i really think it can be done
--Use the Memory sticks as another memory card: save files to the PSP and whenever you need to load, connect it to the PS2 (a little unpracticle, but it would give you a 512 MEGABYTE MEMORY!!!)
--Take pictures/videos of cool stuff in the PS2 game and save it onto the PSP so you can show friends how awesome you are at Tony Hawk Underground 2 (not that they care)
