I thought the next game would be about Abby and Lev, and whoever those people are on Catalina Island that they found out about on the radio. However, why make up something and not continue it? Maybe the remake is just a separate thing. Although to be honest, not a lot of fans really took to Abby after the leaks. Trying to force her upon us as a playable character was perhaps not a great idea. But as a fan, I can admit that any parts with Abby were actually totally brilliant.
Why do a remake anyway? The premise of the original game and the HBO series is practically identical. After all, they're both about Joel and Ellie. So yeah. This seems like a major cash grab.
Unfortunately, consumers who call these games cash grabs, still purchase them anyway. These companies know that we are suckers. So therefore, they know they can make a quick buck from banking off of familiarity.
