I enjoyed Inversion for what it was, a goofy Gears clone that had someone else's cute sci-fi story idea raped, disemboweled, and splayed all over like a serial killer wearing someone else's skin. The shooting is just fine though.
Pac-Man 256 is a cell-phone game, but a decent PC port, really.
Assault Horizon was borderline unplayable. I couldn't do it. Normal Ace Combat is horrendously overrated but the hate on Assault Horizon is deserved a thousand times over.
Enslaved has a great story, great environments, absolutely amazing acting (Serkis can do more with two words than a lot of other VAs can do for a whole game.) and probably the most disappointing, awful-ass ending I have ever seen. I have absolutely no idea what they were thinking with that ending but it was the biggest blue balls a game has ever given me.
Don't skip the Piggsy DLC, included with all PC versions I think, turns the game into a surprisingly competent stealth shooter and the ending there actually isn't complete garbage.
That said, Enslaved wasn't all THAT good from a gameplay standpoint even in its time. It got away with a lot by having a lot of cool set pieces that worked really well with their cinematography and a few impressively open levels. The only thing I remember specifically gameplay-wise from Enslaved was the segment where you did a bunch of Ass Creed style platforming to chase a butterfly for no reason and the voice work was so perfectly in sync with what was going on that it made catching that pointless and irrelevant butterfly seem like the most important task you could be doing at that juncture.
