Believe it or not, I am going to go with Crash Bandicoot. I know, I know, I am completely predictable but nevertheless, it is the best series of games out of the three.
Crash Bandicoot is not only my favourite series of the three, it is one of the best series of games ever to hit console gaming. Sure, you have Halo and Grand Theft Auto and Call of Duty now but Crash Bandicoot is still one of the most fun series of games I have ever played. I played it as a very young child and have completely fell in love with it from the first moment. I hav both of the games that have been released on the XBOX Live arcade and I still play the regularly. Yes, Crash was supposed to be Sony's answer to Mario and Sonic and although he never reached those heights, it is still a fantastic game series.
However, just like Mario and Sonic, Crash has become stale and over-used. I know you might kill me for that Lee but it is true. Just like all great video games characters, Crash has become the proverbial cash cow for developers and has been tarnished into the ground. However, I will always look back upon the first few offerings of the series as the best and they will always hold great memories for me.
I would rate Spyro next as it is the only series after Crash that I have played to any great length. I did play some Rayman but it was only the original and I never played it for an awful great amount of time. Spyro, on the other hand was a game that I just could not escape. My brother loved it and played it constantly. It was a decent game and it is my number 2 because of my lack of playing Rayman.
