I have three younger brothers. We played A LOT when we were younger, expecially on the PS1 and PS2.
I remember games like Crash Team Racing or Crash Bash, those were the games we played the most. But there was also Rampage 2, a game about giant monsters rampaging a city, Micro Maniacs (a racing game with really tiny shrunken people, had a lot of fun with it), The Simpsons Wrestling, Star Wars Battlefront 2 (the old one! It had splitscreen), various Dragon Ball games...
Lot of matches against each other, lots of house-made tournaments, countless hours wasted at playing for entire afternoons...
Ok, seriously. I'm having too many memories, and I apologize if I shed a manly tear.
