It obviously just comes down to preference.
I'd nominate Bioshock as being the most overrated. Possibly GTA IV.
Journey is one of my favourites. The soundtrack is absolutely incredible and was perfectly synced with the beautiful visuals. The movements were satisfying and I liked how it was open to interpretation. Its just a very unique game.
Its only something I would play through once or twice though, similarly to how you can watch a movie and really enjoy it, but you know you will never watch it again. Its kind of a once off experience.
You can't possibly think journey is better than gta4 or bioshock, thats just crazy. Those games are much more open, have much better mechanics, varied gameplay, s much better story, not to mention longevity, voice acting, writing, etc all you do in journey is walk forward for 2 hours and thats it.
Journey can't be compared to big AAA games, in no way shape or form. Journey is at best a 10dollar indie game, even tough I'd never pay that much for it.
