Love this game to bits. I always use to replay my fav scenes in the game over and over. War and the Matrix chapaters were really fun to play through =).
This game lasted alot longer for me because of the multi player. Me and my friend would stick it on Colours (Capture the flag) Then just prevent the other team from getting it and rack up the kills. Going into the sniper tower and putting a hole into the head of those little furry balls of fluff was just ace.
Unfortunately no, because Rareware was bought by Microsoft. This is another great game like Goldeneye 007 that we won't be seeing on VC :[
Rareware did mention that there is a possibility that it will happen. Also, Nintendo apparently prevented Goldeneye 007 from appearing on the Xbox LIVE Arcade. Besides that, if Nintendo was given the all clear to put these games on their service, I doubt very much Conker would be amongst them, unless it was serverly censored.....
But then again, I think about High Voltage Software and their WiiWare title Animales de la Muerte, which is very similar to Conker in terms of violence.
..... what would be very unlikely is if Rare and Nintendo added an online It's War multiplayer mode and stuck it on WiiWare. That would be worth all the Wii Points in the world!
