Real Time Strategy games have never worked well at all on any other system except PC--forget about consoles or handhelds. But I picked up the Nintendo DS and my head is swimming with the possibilities this system presents for RTS games, especially Star Craft, because of its older technology, should be easier to convert to a DS version.
What makes the Nintendo DS so perfect is the dual screen and touch interface. Console versions of RTS games are so bad because you just can't navigate menus/maps well with a stick or thumb pad. But with the DS, the there are a number of ways you could implement an RTS. . . primarily the touch screen is perfect for instructions, relocating the map, drawing patrol routes, grouping units, etc.
Not to mention the DS has wireless(or wi-fi?) capabilities that could be implemented for multi-player or online via-handheld. Games like Advance Wars demonstrate a market for strategic/tactical games, and no one does strategy like Blizzard. You bring Star Craft of War Craft to the DS, advertise in PC mags, and you WILL squeeze even more money and play out of these popular series.
It would be dissapointing for the first truly unique and wide-open pieces of hardware to not get these blizzard games. It is clear Nintendo has no idea what to do with this great system it has created (Mario 64 puh-leeze.) So please Blizzard, take up the slack. You WILL be rewarded.
