Litecoin was a copy of Bitcoin, only noteworthy thing that was changed was the hashing algorithm. How fast coins are generated and how many in total is really irrelevant.
Yacoin also just changed the hashing algorithm so that it could be CPU friendly at start. And with the preannouncement of start it was more fair than any other altcoin till now, only coin start that was more fair was bitcoin itself. And the bugs of Yacoin will be sorted out if the coin survives, and I think it will, since there was absolutely no premine (20 mins after launch it was on block 49) and a day later you are still able to solo mine it.
