I can't say this will be a great must have game for the DS I mean if we really wanted strait up ports with no graphical improvements or gameplay improvements we'd all be playing our PSPs....

Seriously thouogh I am a fan of the series and RE is what made my buy the cube before the PS2, it was like ooooh look at Metal Gear Solid 2! He can shoot up a kitchen, then I saw RE and was like OMFG look at the flowing hair on the zombies. I think the controls are pretty solid, I did like how RE: Remake had a 180 button for quick turns but the controls have always been pretty easy to grasp.
*Edit
Oh and to finish my thought, yea it's a port, nothing really new, the original wasn't that great anyway, RE2 is when the game came to shine so that pretty much should sum up this game. The new mode looks kinda lame, pointless reasons to use the stylus? Not sure, only way I'll know for sure is to play the game all the way through on both modes.
