Two were guessed, so I’ll give a second hint for these;
#50: Due to the graphics being up to anyone's imagination with these old games, the European box art made it as if we'd be in the Wild West, while the American’s thought it was the start of the next century. If you're Veknoid, you've guessed this plenty of years already.
Hint 2: Maybe it’s because of two things; you look like a cowboy, but your bullets ricochet off the trees (I guess the triangles are trees), which is pretty sci-fi.
#49: Something happens during half time in this old sports game that doesn't happen in real life on the continent where this sport is most popular. I guess Nintendo didn't know.
Hint 2: Because cheerleading is not a thing in Europe.
#48: This game is extremely obscure, but is, unknown to me at the time, a clone of an NES game where a sorcerer, the player, creates blocks to solve puzzles. I'll take the NES game as an answer. Guessed by Darashiva
#47: Features a character you just want to shoot. Guessed by Darashiva
#46: You are called a rookie because you're a new pilot, which strangely is also your name, even though you've already had an adventure.
Hint 2: Still at one point you get a teacher, where you should “follow [his] lead, and do as [he] say”.
