I've played a good amount of games and i've felt disappointed by a 10% of them. But among all of those i've found things i really dislike. A long list.
1: Kid Friendly games that turn out to be too hard. One of the offenders is "Donkey Kong Country: Tropical Freeze". Its predecessor for Wii was hard as well, especially in Hard Mode" but nowhere as hard. There is a line between "challenging" and "unfair". Not everyone is a videogame genius who has too much time to spend with them. It was even a good game anyway.
2: Games that are too easy. Kirby's Epic Yarn is an offender. Now i understand the extremely kid-friendly feel of Kirby (well, sometimes the series gets creepy but never scary) but Epic Yarn is just Game Over-less. It's not a necessarily bad game anyway
3: Repetitive bosses. Oh god, when bosses are recycled over and over is just cringeworthy. This happened with a good game like Sonic Colors, where world 4-5-6 bosses are nearly identical to the world 1-2-3 ones. And speaking to "not very good" games, i remember playing "Harry Potter and the Chamber of Secrets" PS2 version and had that Tennis Style Boss appearing just everywhere. Some of the game aspects were fun but, eeew...
4: Bland cutscenes. Seriously i just can't stand Harry Potter PS2's cutscenes that just don't give life to anything, they're cringeworthy. Also the PS4 Ratchet & Clank is an offender of this. Compared to the PS2 games cutscenes (I didn't have a PS3, unfortunately) they're dummies! A lot of PS2 games have very bland cutscenes, seriously. So you wonder how were MGS2-3 possible, if PS2 games' cutscenes sucked so much. Still mentioning the Harry Potter thing...
5: Loading times. Shoot! If i ever go inside another area i have to wait 20-30 seconds just to play it. What if i did forget something or if i did in that area by mistake? Just boring.
Rayman 2 for PS2 has this as well, even if slightly shorter and even if it was a good game. Well, a lot of games have this problem, you know, i won't mention Sonic 2006 because there is so much wrong with that game that can be described by
one scene.
6: Vast and empty maps. In the Harry Potter game i'm talking about you can fly with your broom freely so you can reach unreachable parts of the castle... that feature nothing at all. Seriouly, there is literally nothing you can do in that map.
Talking about modern games in general, today, maps are just too big but with little to do. Assassin's Creed series is just a great offender. There is a reason i loved Assassin's Creed 2 and Brotherood (Revelation was fine but it's clear it marks Desilet's departure from the series, poor Desilets): their maps were big but not too much. But the real offense is AC Unity. Leaving the fact that after beating the game i just lost any interest to complete the games, Paris is just too big.
And only because something looks realistic doesn't mean it is any good. If i want to see a perfect replica of Notre Dame... well, i'll buy a trip to Paris and visit the real cathedral instead. AC Unity has so many wrong with it, besides the boring colossal map, like...
7: Bitter, generic, pointless plot: When i play a videogame i just don't feel like playing "Romeo and Juliet: The
Edge Videogame". AC Unity wasn't a good game alone, the plot even contributes to make things worse. Assassin's Creed has never been known for being light hearted but Ezio's Trilogy is just good. There is a reason AC Unity has caused so many controversies (Mars Attack), just like AC3. Maybe i'm probably stuck up with Nintendo Games anyway, lol. On the other hand...
8: Games with no plot at all. As good as Rayman Legend was, i hated the fact that it was just plotless. I mean, it starts with one but it's just an excuse to "let's go adventure!!!". There must at least minimal progression to story, even with a simplistic one like you see in Mario Games. Rayman Legends had none, though. That's why i kinda preferred Rayman Origins, in terms of gameplay. It felt much more original and richer. Also more challenging. At least in Legends the climax is offered by settings and soundtracks. Ubisoft, heh.
9: Games that are too short. In this case, i'll put Wario World. Gee it was so short. But i admit the game was pretty. Epic Mickey 2 was felt very short, so anticlimatic and so unpolished. And speaking about Epic Mickey...
10: when games don't let you revert back to a save. Sometimes, especially in "choice-ridden" games, you may want to go back to a save. Even Undertale, one perfect example of "choice-ridden" gameplay, lets you do this (it's actually one of the main points of the game!). Epic Mickey doesn't. If you did something wrong with these clunky mechanics you can't go back to a choice. If you didn't like the consequences of some of your actions or just want to see both without playing the game ever and ever, you'll have to deal with it. It's just unfair. Someone may like it but there should be an option for it.
But i've never heard about Warren Spector (the author of Epic Mickey) like an humble guy open to criticism. Probably he thought "no my game is fine in this way i don't care" and it was clear with Epic Mickey 2, where most bugs from the predecessor weren't got fixed.
Probably there are other things that annoy me in a video game but there are among the main. I have to admit that, despite Playstation games, Nintendo games have never disappointed me totally like a game like AC Unity did. I'll even put Shadow of Mordor, which had a very short main campaign and a quick time event as final boss... seriously
