I have a lot of nostalgia for Full Throttle, so being objective is a bit difficult, but in short: It is one of my favourite adventures, but it's not that great of a game. Full Throttle oozes charm and style like no other adventure game, but its gameplay is lacking. It is in general quite short, its puzzle can be questionable, it lacks interactable objects and it doesn't always feel like it respects its players time, both in smaller aspects and with bigger things like the bike combat sequence that will outstay its welcome for most, especially for new players. On a positive note: Full Throttle still does do a lot of very unique things for the genre and tells a unique story with unique characters quite well and for that it's definitely still worth playing. And the remaster? Honestly, I'm not convinced it's an upgrade. I don't like the slight changes in the art style compared to the original and the audio isn't as good as it should be, with harsh transitions between scenes and sometimes questionable audio mixing. So if you already have a old copy lying around, you might as well just throw that into ScummVM and save the money for the remaster. But please, play it anyway. It's fun.
Compared to its predecessors, Broken Sword 3 is a disappointment. The change to 3D is a significant step down compared to the beautiful 2D art of the first two parts and leads to changes in the gameplay that are not to the advantage of the game. Because the gameplay was changed to make "the most" out of the possibilities of 3D and the awful new controls, classic puzzles are quite weak (for example the old and worn out "newspaper under door to get the key") and mostly fairly easy (with some illogical ones thrown into the mix) and are paired with far too many tedious crate pushing puzzles and jump-and-"run"-sequences that are significantly hampered by the awful camera and the slow controls. But, if you manage to work through that and accept that you will run into some walls after camera changes... there is a decent game to find here.. The story is interesting and fits the rest of the "Broken Sword" universe, the presentation isn't pretty anymore but still decent and the voice acting is - apart from some henchmen - quite good. Especially George and Nico work quite well and manage to save the game from being a complete failure. Just don't expect anything as good as its predecessors. (Two freezes btw. So remember to save.)
Very well written adventure with an interesting story line, pretty graphics, good and never unfair riddles and great music. A delight to play for all the adventure lovers out there. Biggest downside is its length of about 5 hours, but it's time well spend.
