Second set of hints for these five. Like I said I think I'll post them by five, so when it's day 46 I'll post these and then move on to the next five. Anyway;
#50: You think there's only one, but then it turns out there's another. How many of these cruise ships are there anyway? Guessed by Mnementh - Resident Evil: Revelations
#49: Funnily enough this game's setting is also a cruise ship, even though it's unrelated and I personally don't have anything with cruise ships.
Hint 2: This cruise ship however, has been invaded by modern day pirates to kidnap the president's daughter who is onboard.
#48: No cruise ships in this one, but there is a train to a puzzling town.
Hint 2: There is a fun side-quest throughout this game, which I could identify with as a tea-lover myself. Guessed by Veknoid_Outcast - Professor Layton and Pandora's Box
#47: The vehicle theme seems to continue coincidentally, but this time it's just car. Pick people up, drop them off and take the shortest route possible. Guessed by Mnementh - Crazy Taxi
#46: Cheerleaders during half-time aren't actually a thing in this sport, at least not on my continent.
Hint 2: There's also usually 11 players on a pitch instead of 6. Guessed by Veknoid_Outcast - Soccer
