I think that would come to 4 GB.
:smile2: Ultimately the idea is that the final boss is just a pile of thrash who got his AI from ET cartridges memory, but the AI itself would be very limited and would include an AVI video in HD which you can see when you defeat him, transferring then the data to your laptop.
The ending would be 1 h 40 minutes of HD video which was inside the final enemy's AI, an he would only have less than a KB for true AI. So his AI would only consist of the parameters: kidnap, smash, hit.
Hah, I haven't written a serious line of code in over 5 years, I think I'm way out of the game programming loop by now. I think its awesome in the video you linked that Howard Scott Warshaw was there. Truth be told I thought ET wasn't a bad game really, I enjoyed playing it as a kid. Yeah getting out of a well only to fall right back in was kinda irritating, but aside from that it was reasonably fun. I can think of dozens of other games that are far worse than ET was.
Well, your programming skill of the current era would be more than enough to create a classic game like R-Type with much better code! I think.
I could imagine you making a R-Type game with simple graphics but amazing gameplay and depth, like... R-Type. (recently watched a video of a guy completing R-Type 1 and R-Type 2, with a single credit)
The trick in the game is memorising some patterns and knowing some tricks, also keeping ALL the power-ups you need the entire playthrough. If is a game where if you die once, you won't be able to complete the game.
But intelligence and memory (where to place your ship) come to play if you want to complete it, it's not like modern shoot em' ups where the whole screen is filled with meaningless bullets.
By the way, if ET wasn't that bad for you... which game would you bury in the desert?
