Completed two games recently and was disappointed in both.
Telltale's Game of Thrones series started off pretty strongly, the conclusion to Episode 1 pretty much nailed on what makes the GOT series so interesting to me. But episodes 4-6 descended in story telling quality so badly that I just didn't really care about my choices anymore, because I could very clearly see through the cracks. I can see that ultimately none of my choices mattered because I could tell that people would have survived or died regardless of what I chose. This was all too apparent in a revelation at the end of episode 5 to the point where it actively broke the story. Because this 'twist' had to play out no matter what, the reasoning why this particular character had to do what he did made absolutely zero sense and went completely against his characters. Ultimately the writing wasn't as strong either, I didn't really care for any of the characters, most of them were cut outs as replacements for the Starks but without the character depth or progression. Shame, because Telltale's Walking Dead is excellent in this regard so was very excited for a GOT adaptation. Plus, the engine was sooooo bad. I played it on the PS3 so more fool me I guess, but good lord the techincal issues were so bad. Insane loading times characters in the background just standing completely still not even breathing and when the shit hit the fan all the game's audio except the voices had cut out entirely. Transitions between QTE's took tens of seconds so I spent looking at still frames rather than actual gameplay, dialogue was cut when trying to catch up. I won't be buying another Telltale game until this engine is fixed.
The second one I was disappointed by? MGS5. Now let me clarify and say that my disappointment lies in the story aspects, the actual act of playing the game, infiltrating bases etc is so good, easily the best playing game of the series. I had a few issues with the gameplay (very barren open world, no boss fights, takes far too long to choose to do a mission, load the game, fly in the helicopter etc, some stupid missions especially mission 46, holy fuck that's the worst mission maybe ever) but my main gripes were with how it all ended. I can't even begin to explain here as anyone who hasn't played the games will be confused. Let's just say, I came into MGS5 expecting gaps in the MGS timeline to be filled. So we can see how Big Boss went from the hero to the nuclear weapon using villian. And I didn't get that when the credits rolled. In fact, in terms of the timeline you can go from MGS3 to MGS1 in a straight line pretty easily. The events of Peace Walker and MGS5 don't really matter or have that huge an impact on your perception of the rest of the games. And I would be fine with that if the actual story was told well but it wasn't. Very little character development, the villian of the game was sorely underused and the way the game was designed with it's open ended mission based approach seems to have hurt the game's pacing a lot. The problem actually is that the ending to MGS3 is so good that it kind of backs up my idea that Peace Walker and MGS5 are unnecessary. You see Boss turn down that handshake at the end and you can make your own assumptions on why he turned. Overall, while it's a great game in itself, if the story is really lacking, it doesn't feel like a good Metal Gear game. You know? To think it could be the last one we ever get is also disappointing.
