Ok, so after reading through some of the post above me.. I tend to agree with people that suggest Fallout 3. I really enjoyed the game world in it and the overall experience was great. The only problem with this however is the lack of continuing characters or a regular cast.
Then theres the rising epidemic of Zombie Games/Movies/Books/Media that seems to have flooded the market recently, which basically rules out anything to do with DayZ or Dead Island (Walking Dead basically covers everything)
My pick for this (and I cant believe Im the first to bring it up) is GTA: San Andreas.
Now, before you criticise my point, hear me out:
- major character development/well structured characters.
- regular cast.
- betrayal.
- wouldn't need massive budget to make it look good.
- plot twists galore (if you count the trivial stuff).
- potentially never ending.
Other than that, I'm going to state that I don't think either in the video would make a good tv series.
- Bioshock, whilst being a really interesting world has very little interaction to offer, especially with other characters.
- Mass Effect, whilst having a plethora of characters to run through. It follows a fairly non-linear storyline, and its been done already in countless other shows.
