If Reflections capitalize on their Driver franchise, I seriously think we have a contender.
It set the stonemark with Driver 2 for the PS1, free roam and car jacking and I only think if they dedicate themselves they can cross over. Not very possible, but its plausible. I wonder if they'll make a sequel anytime soon for the PS4...
Though Rockstar needs to deliver us a 4K HD Vice City, for the hell of it. GTA3 was a shining star, but Vice City when it lauched, whoa. I still remember how thrilling it was to collect all the cash from properties in a single day (24 minutes) and start all over again.
All we ever wanted is interactivity, GTA Online brought us that, but they're just going nuts with this online thing. We already pay to have internet connection, pay to buy the game, now you have to pay for everything else inside the game or else you'll be risking yourself to having a very unhappy and deadly gameplay. If we were able to become "citizens" and each having their respectful jobs (robbery, kidnapping, car jacking, as well as other legit jobs) I think they could make it worthwhile.
Else it's just gonna turn into another deathmatch until people's interest goes to something else and the online GTA has a demise.
