There are dozens for videogame franchises out there, but for every franchise that churns out a game every year such as Call of Duty or Assassin's Creed there are some franchises that lay dormant for years(a couple famous examples being Duke Nukem and Half-life). Here are three that I would like to see return after a few years of silence.
Spyro the Dragon
Spyro has appeared in the Skylanders games, but the last true Spyro game was The Legend of Spyro: Dawn of the Dragon in 2008. That means the series has been dormant for almost 10 years. I think a rebooted trilogy, maybe featuring an adult Spyro, could be a good idea. At the various least I would like to see if get the same treatment as Crash Bandicoot did earlier this year with a PS4 remaster of the original Playstation trilogy(which is rumored to be happening). A Crash/Spyro crossover game would also be cool to see.
Another franchise that has been dormant since 2008 after the release of Mercenaries 2: World in Flames. There was a rumored third game called Mercenaries 3; No Limits, but after Pandemic Studios closed down the franchise hasn't been heard from. I would like to see EA try to revive it, maybe with a game set during WWI or WWII or even a game set in the future. Mercenaries 2049 has a nice ring to it.
Destroy All Humans!
Known for it's irreverent humor and spoofing normal game and movie conventionss Destroy All Humans! is yet another franchise that went dormant in 2008. Like Mercenaries, Destroy All Humans, suffered a studio close with THQ. Luckily Nordic Games bought the IP and has said they are "evaluating options" So far we have only gotten a PS4 port of the first two games, but perhaps a new game is in the works. I would love to see one set in the '80s, perhaps titled Destroy All Humans!: Crypto Strikes Back.
Those are just a few ideas for videogames franchises that could be revived. Which videogame franchises would you like to see come back?
