Not going to happen with prototype. Activision had plenty of time to revive these games. They didn’t. They didn’t see it as guaranteed revenue like Candy Crush or COD annually.
Microsoft purchasing Activision is not going to change much. Because Microsoft also likes guaranteed revenue. Which is why they continued to milk Gears, Halo and Forza. Or purchased Mojang for Minecraft. They as well didn’t bring back many of their own games. Because they aren’t money makers.
Sure, you’ll see them throw a bone here and there to say they are using the purchase. There might be a game or two to test the waters. And they’ll bring characters into other games possibly as micro transactions on console and mobile.They’ll use those characters like Konami does for casino games. Especially on mobile.
But as soon as they see that no one is engaged in those few attempts because the community that enjoyed and purchased those games more were on a different console, they’ll shelve any future attempts and continue on with the same rotation of guaranteed money makers.
If those other franchises were money makers, they would still be around getting releases and not in a back catalog collecting dust. Where gamers wonder why they aren’t brought back.
