Even though I have only known Interstate '82 from the You Tube videos of its gameplay and cinemattics, from playing the demo, and from a advertisement for it in a PC game magazine, I don't find the concept too terrible. Yes, i liked the combat/driving/armor system of the first game better. I liked the idea, though, of I'82 deriving influences from Miami Vice and other 1980s crime shows. I also liked the idea of having all Taurus and Groove undergoing an existential crisis after the end of the '70s, and having to cope with the brutality and empitness of the '80s. It was surprising to me that Activision used a few cut Devo songs for the soundtack, but it seemed appropriate for this particular story they were tryin to tell, because Taurus and Groove pretty much were devolving, since it was no longer cool to be groovy and swingy in the new decade (kind of like what happened to Disco performers after everyone said that Disco sucked).
On the other hand, the more I learn about the plot, the more it does seem ridiculous (like having a villain who sounds like Christopher Walken, and dressed like someone from Sgt, Pepper Lonely Hearts Club Band). Since the game is set only three years after the '70s ended, I don't think it was necessary for Activision to do away with the Funk-styled soundtrack. I mean, Magnum P.I. was done in the '80s, and it had a very 1970s styled theme song, so why couldn't Interstate '82's soundtrack still remain Funky?
I also think there was a lot of wasted potential for the new gameplay element of getting out of the car. It would have been really cool if, once out of the car, the player could attempt to hide in the alleyways, behind trees, rocks, canyons, and be able to snipe at the car, while still out of sight of their radar (depending on how well you could hide). Another cool idea would be to interact with other civilians, and to be able to enter the buildings and find civilians hanging out in them. There could even be a few foot-walking missions, inside and outside, to add to the interactivity.
On the whole, they sould have kept the original armor system, physics system, and the first perspective mode as well. If I wanted to remake it, I would have opted to do it in an engine similar to the original tesselation engine for i'76, and kept all the original gameplay elements, while perhaps retaining the plot of '82. Either that, or we may need to find somebody today to do an Interstate '77, Interstate '78, or Interstate '79.
