Yeah, The Two Thrones and The Warrior Within. Honestly, I find it extremely hard to play these games after playing The Forgotten Sands because they just feel so primitive in comparison. I got the trilogy on the PS3 and I was only able to complete the first game which did take me a while since I stopped playing it at one point. I started the second game but I don't really care to finish it. The Forgotten Sands has better flowing combat and great quality platforming both of which are heightened by the game's unique abilities.
Anyway, another game I find criminally underrated is Alan Wake. The game didn't find success until it was too late so now production on Remedy's much anticipated sequel has been brought to a halt. The gameplay was pretty simple but the design, enemies, soundtrack, and story is what really makes this game. Though not technically a survival horror game, the narrative is very Stephen King inspired while creating a sense of dread and isolation throughout most of its story. Ammunition and other helpful items are quite scarce too, encouraging players to use the environment as best they can to their advantage. Alan Wake is truly a hidden gem of the last generation.
