Chronological order by played. I was a child in the 00s.
Super Mario Bros (NES). My cousin borrowme his NES and the first contact I have with videogames was Super Mario Bros. I don't remeber much of it, but I guess It was fun as hell because even my parents played it. I got the SNES later for a couple of months, but I didn't play any remarkable games.
Age of Empires (PC). The game that got me into PC gaming. My father bought a PC for job purposes. I grew up playing solid tittles as Unreal Tournament, Quake II, Starcraft, Pharaoh, Civilization III, but man, I played Age of Empires a hell of a lot. The gameplay was extremely fun, and it was so difficult for me as a child that the game last me months. Then my parents bought me the Collectors Edition with AoE 1 & 2 and the expanssions. I remeber studying the booklet with the trades of each civilization while I was in the beach. I probably played AoE II the whole year.
Final Fantasy VIII (PS1). I got the PS1 at the end of its life cycle, and I had troubled finding games in the local stores. FF8 is the game that bough me into RPGs and I totally love it (I didn't play FF7) I spend more than 100 hours and the playtime counter turned red. Great story, interesting characters, fun combat system, amazing BSO, I learnt what grinding was... ¡and I enjoy it! After playing this game, most of the others games seemed to lack depth.
Fable (Xbox). While all my friends were bragging about his PS2 and talking shit about the big black box, I ask my parents for the latter in christmas. Most of my console gaming memories are attached to it. The graphics were freaking awesome and buying was the right choice, even though my friends kinda despised me for that. Fable was the 3rd game I had. I love the epicness, the music, the humor... and the charming atmosphere. Although it felt incomplete. Then The Lost Chapters expanssion came out and playing again with all tied up was very satisfying. I still have the Anniversary Edition in my backllog, but it seems like they remove the cartoony design that characterizes it.
Gothic II (PC). For my, this is the best game of the best saga of RPGs (1, 2, & 3). A total hidden gem. The world seems perfectly tailored and the open world is amazing. I was totally sucked into its atmosphere... The character developement is challenging but rewarding. You can easily die fighting the first monsters and the are no annoying level scaling. This game was able to make me feel like I was the character of the game, and I think that is the biggest achievement for any RPG.
I was a PC and Xbox child.
