Well, for me it started very easy. I was on some kind of school tour (that is not true, cause this wasn't organised by school. However you can think about school tours, mix it with Polish schools, Polish teachers, and Polish students, and get Polish school tour. And after this, you will see something very similar) and many more of us were bored. Yes, you heard it good. Bored. And after few days, one of our pals get out his GBC with R1 cartridge.
When most of us tried to became master of jumping, I personally tried to understand what was game about. After six months, I came to my school friend's home (nameday party), and I played R2 on his computer. I was a bit shocked, when I realised that Rayman hasn't got limbs and legs.
After a few years, games (educational) that I already have beaten were so boring... I bought RM for something about 10$ (today, that time it was 20PLN). I enjoyed the game, especially music. Then I bought R2 (for 15PLN) and I really got excited.
The most interesting thing is how I bought R3. At the moment, seperate R3's were very rare and costed about 50 PLN, but there was 10th Anniversary with very similar price. You know what I have do? I bought R10A, and then sold R2 and RM for something about 20PLN.
After all, I am looking for R1 (for PC, of course). However, I am not sure will I find it any time in Poland... if ULR/REL will not work.
