I would like them to fix the 60 fps cutscene issue. None of the original cutscenes were designed for that high frame rate, they just artificially sped them up which makes a lot of the Halo 3 cutscenes look weird. I’d at least like a proper port, kind of like what Nixxes has been doing for Sony games on PC.
I don’t know how much research/traction this idea has, but I’ve heard of a reverse hybrid system that seems to be a good solution in my mind. The electric engine operates the drivetrain, and the combustion engines runs continuously at its most efficient configuration to act as a generator for the electric engine. There’s still a battery to store power, but the combustion engine will last MUCH longer due to consistent/stable RPMs and usage. Plus, you get the advantage of electric instant torque.
