for nmh 2...i think the plan to use wm+ was scrapped off as far as i can recall properly

as what's a m+? well, it's a peripheral device...sorta like your nunchuck, but its main function is to map 1:1 motion control

not many games use this device at this point of time, however, some famous games like Tigerwoods 10, Grand slam tennis and Wii sports resorts are the worth mentioning ones currently in the market

future games like red steel 2 and zelda wii are what i have in mind utilizing wm+ in the future...of course, there will be more games utilizing this device...but i can't recall of any more for now

is this a must buy? well, if you really are looking forward to play zelda wii and wii sports resort, then it is a must buy, as the games will only work/load when you have a wm+ attached to your wiimote

also, if you like a tighter feel to your controls, then you can purchase this as well (only if the game recognizes the add on, meaning that the developers made their games compatible with the wii motion +)

otherwise, you can forget about purchasing this as...there are many games which doesn't really need to use this to function properly

how much does this costs? the last time i check, should be around rm80 till rm 120...more likely you'll find shops selling this at around rm100 ea there though
