There are so many ips and so tough competition out in the market that many good ips lost there importance. many games we are not going to see in next few years. but these are the games in my opinion are not coming even in 10years.
1. Warcraft 4 (blizzard got its hand full with starcraft 2, diablo 3, WOW and Titan)
2. Age of Empires (i dont think going to see any RTS from this series though an MMO is under development).
3. Commandos (Not going to see any RTS game, may be different genre, where are you pyro studios?)
4. Quake 5 (Raven ruined quake 4, let's hope id takes back and do something, but possibility is low due to doom 4, rage sequel)
what are your thoughts guys?
