Machinarium vs Portal 2
Machinarium
Machinarium is an award-winning, puzzle-adventure game where you'll need to help Josef the robot rescue his equally robotic girlfriend Berta from the Black Cap Brotherhood gang. The game features plenty of logic-based puzzles along with a nice smattering of mini-games and adventure-based quests. The hand-drawn art style used in this game is perfectly apt for the overall theme of the game as well. Couple that with an epic soundtrack and you'll get a level of immersion that you might have never experienced before (or perhaps rarely) in a puzzle-adventure game. At the end, you'll actually feel for Josef himself.So, if you're up for a rather depressing and yet heartwarming puzzle-adventure game that will give your brain a run for its money, this is definitely the game to buy. If you get the chance, you should really try it.
Portal 2
Portal 2 follows in the footsteps of the award-winning original while continuing the story of Chell and Glados. Now with both single player and a 2-player cooperative mode, Portal 2 ramped up its game with a plethora of new, challenging puzzles, a storyline that's a lot richer than before, and more advanced and realistic physics that will govern your gameplay. Interestingly, the game also includes editing tools, allowing players to create their own puzzles which can then be shared for all to enjoy.Portal 2 is definitely a much better game in the series and if you fancy giving this franchise a chance, you might want to jump straight to Portal 2.
