Summary: The Sly Collection was a great idea because a lot of people either skipped that series entirely, or played one of the games and missed out on the others. The Jak Collection was necessary because, for whatever reason, Sony has let that series sort of fade away (despite efforts such as Jak X, Daxter and Jak & Daxter: The Lost Frontier). But Ratchet & Clank has never faded away from Sony; Insomniac has gotten 4 games out on PS3, and soon to be 5.
Summary: The first game was terrible, mainly because of the targeting system, unlike most games where you press a button to lock on to enemies, this games uses an auto-targeting system which is awful because in order to lock on to an enemy you have to have Ratchet perfectally facing the enemy otherwise you just send ammunition of into oblivion, and trust me getting Ratchet perfectally facing an enemy is a nightmare.
Theses original games are much harder then the ones on the PS3

Summary: I had played R&C when it first came out on PS2, and did have a brush with up your arsenal. Then i played all 3 games on the PS3 and was able to finish without to many issues, but playing theses original games i found a lot harder. Up your arsenal is very hard from the start, and if you die you start from the beginning which can some times make it very frustrating the checkpoint are also far a part.
Conclusion: I am a long time fan of the Ratchet series, and brought this trilogy to add to my collection. Whilst the graphical overhaul is indeed an improvement over the PS2 versions, it is almost outweighed by the amount of bugs this game contains that occurred as a result of the conversion and the fact that the release date was really rushed by Sony.
