I first started to watch my mum play Abe's Oddysee demo on the playstation when I was three or four (12 years ago, not long after it came out!) so I have beem familiar with it for nearly all of my life.
I then bought the full game when I was ten. I got to Scrabania (without doing Paramonia) but gave up as I found it so hard (and obviously never tried saving any Mudokons, apart from the dead easy ones in RuptureFarms).
Then in the summer holidays last year, I managed to complete the game fully and get good at it. I bought and completed Abe's Exodus afterwards. In the October half-term holidays I completed AO saving all 99 Mudokons.
Since then, I have been completing Abe's Oddysee many times and can almost partially memorise each part of the game, which is why I badly want a Level Builder so I can make some more.

Alternatively, I would like to forget the levels in Abe's Oddysee so when I complete the game again, it would be a completely new experience!
I haven't bothered to complete Abe's Exodus again so much as it is very long (not a bad thing

) and I prefer Abe's Oddysee more because it has a different feeling when you play it and is much less slapstick than Abe's Exodus. I am planning to get all 300 Mudokons on AE in the next Easter or summer holidays.
In conclusion, I do prefer AO to AE, but I think both games are amazing as they have awesome artwork which you never really see in any games nowadays, they are just so much different to other games and are in a way quite modest, so to speak. I also think that they give you a good feeling when you play them.
P.S: Another thing I find strange, is how I look at different threads and it seems that alot of Oddworld players (like myself) started playing at a young age (under six). Has anyone else noticed this?
