The gaming market is full of wonderful franchises to choose and play but not all of them are ongoing. There are duologies among them--particularly those that deserve to be trilogies if not long-running franchises. Here is a list of some video game franchises that fit the bill.
Condemned series (PS3/Xbox 360/PC)
Hands down, Sega's ‘Condemned’ duology was one that deserved to be a trilogy. The series consisted of a couple of first-person psychological horror games— ‘Condemned: Criminal Origins’ and ‘Condemned 2: Bloodshot’ —that combined forensic-style puzzle solving with improvised melee combat. Unfortunately, there hasn’t been a follow up since 2008 because the sequel had failed to sell enough copies, plans to greenlight a trilogy became financially unsound.
Left 4 Dead series (Xbox 360/PC/Mac/Linux)
It’s been over a decade since ‘Left 4 Dead 2’ dropped and the video game still has an audience. However, there’s growing concern over its longevity. The first game deserves its praise for kickstarting the zombie slaughter fest but expired due to a shrunken player count. And while it lives on as a free add-on to its successor, it too will eventually expire. Furthermore, Valve admitted that ‘Left 4 Dead 3’ isn’t in development and that makes sense given they “can’t count to 3.”
