The lights are on
While I love the franchise, there's no real reason to go back to the PS2 era games, unless you really need your fix of a few more Captain Qwark one-liners. A nice graphical polish, but these still look positively ancient compared to the Future titles.
Whether a longtime fan or someone who has never played the franchise, just get Tools of Destruction and A Crack in Time (probably can get both for the same price as this), and you'll have pretty much the full gamut of R&C game play. Beyond that, you'll realize that until ACiT, the series stagnated pretty badly after Going Commando.
