Do you think Halo should follow in Quake's footsteps and make a battlefield esque game? I think that would be awesome and they already have a large selection of weapons with a rifle, sniper, shotgun, and rocket for each race so I think it would fit well.
For all the people saying "no" to a new Halo well it just isnt business smart to give up on a SUCCESSFUL franschise.
Dave it would be like nintendo saying "lets stop making mario games"..
Halo has been the staple of the xbox I don't see the franchise going anywhere.
The game sells, and gets good reviews and has a HUGE online population. Despite it seems a lot of people have negative opinions of the game here... Halo 3 included nearly everything that should be in a FPS for multiplayer in my opinion. Even if you didn't like the "gameplay" having online multiplayer that is easily accessible, the ability to play with friends in the party system, the ranking system, reviewing gameplay through the threatre, creating gametypes in forge, downloadable content, uploading videos with online stat tracking, etc is setting a bar for the condole industry and the FPS genre (on the console).
I dont think we will see a new FPS Halo game for a good 3-4 years from the release of Halo 3.
Even then, I have a hard time imagining them making a Halo 4...the game ended. Halo wars is a cool step I am a huge RTS fan and I ensemble studios was my favorite RTS studio.
I think a prequel isnt out of the question but to be honest the guys can't improve the system much beyond what they accomplished. Halo three is more balanced but ultimately is it just a more polished version of the previous Halos.
