My mom made me do school workbooks she got at a teaching supply store over the summer as a kid. I think I was probably 8 at this time. After I got so many gold stars, I could go to Toys-R-Us to pick out any Gameboy game $20 or under. I picked Tetris 2. All the good games were more than $20. Was it great? No. Is it still special to me? Yes.
I remember being taken to a local video game store that ain't around anymore and being able to pick out Oblivion. It was the first time I'd played a game quite like it and I bounced off at first, but I kept at it and it's one of my favorite 360 games if not my favorite Elder Scrolls.
This was Pokemon Red for me but my mom randomly bought that and an Atomic Purple Gameboy Color off Amazon for me. This was back when shipping from them took forever, so I has a solid week of just having the game and box to look at before I actually got to play. The hype I set for myself was well worth it :)
