A bit more games, that I remembered:
Dreamfall: The Longest Journey a sequel to
The Longest Journey (which was an ordinary point&click adventure game) became a full 3D game (with a camera behind character's back like in TPS), featured stealth and fighting segments and a couple of puzzle-minigames.
Castlevania 2: Simon's Quest unlike first
Castlevania which was completely linear with stages and bosses, became a game with (semi) open world, where you wandered between towns and castles, entering them at will. In fact
Simon's Quest featured day/night cycle (at night monsters became stronger and towns were infested with ghouls, NPC on the streets could be encountered only during the day), progression system (simple exp/lvl counter, nothing fancy) and two ending (depending on time it took player to kill Dracula).
Super Mario Bros - yes, it is a sequel to a game called simply
Mario Bros. There was no princess, no levels, everything was happening in one room/screen - the task was simply to kill as many creatures coming out of sewer pipes.
Damn, missed that comment!
IwubCheeze: Dreamfall went in an entirely new direction. The "game" is now TTP, all the puzzles are gone and they were replaced with bad stealh and combat mechanics. I never needed a walkthrough for this game because most of the game was just going from A to B. The game told you were to go. On the plus side, this did keep the narrative going but the gameplay was pretty non-existant.
I don't know, I actually liked stealth segments. And a touch of nonlinearity (like made a right answer and you can pass without a fight) was cool.
