Have you ever watched a cutscene? Or read any lore? For starters, RA1 wasn't after WWII, it was WWII. In the opening cutscene for the game, the scientist time travels and removes Hitler, thereby taking WWII as an event out of time. So WWII never happened, and the timeline changed. Korea- and Vietnam-era weaponry came about earlier due to necessity. And the Tiberium universe wasn't post-apocalyptic. GDI is a UN military conglomerate, not a group of survivors. They most likely existed in some form before Tiberium was discovered. As for Nod, they're a terrorist organization. Their tech is based on stealth, hit-and-run tactics, and guerilla warfare. So it's not that their tech is older(though some of it is), it's just that their tactics rely on faster, cheaper weaponry. Am I getting all this right, lore-nuts?
