Might have been discussed to death already.
- Wide open Sandbox. It don't think it can really work, considering the scaling issues. Make the map too small and everything get too close to each other. Make the map too big and you mostly get boring generic filler between relevant locations. 99% of the time, they manage to have both issues at the same time.
- The fact that those sandbox should suddenly be included in each and every single game. (at least AAA)
- Replacing the single 25% game content increase of the Add-on, by a billion of tiny DLCs that only add a white hat or a brown skin.
- Normalization. All games of the same genre should work the same, so we don't risk changing the habits of the playerbase. The time in which most of the games played differently seems forgotten.
- Battle.net and those who followed this example. You have to be online and their server has to be online, every times you want to play your solo game.
- Shown Skill-check, un-killable npc, fake choices, fast-travel free teleportation, voiced PC in RPG...
- Paid mods which 95% of the money don't go into the modder pockets.
- Making PC game for console, with the limited controls of the gamepad...
- I like the Steam and GoG platforms, but i don't like the fact they get that huge percentage of the whole world video-game economy, just because they made the first online game store. Steam and GoG almost have the monopoly of the retailers. At the same time, i don't see the point as a consumer to go in ten other stores.
- Games that rely on grinding and repeating the same little tasks. Gather some woods and metal, make a pick-axe, gather some ore, refine that ore, make another item, then use that item to build other items after you gathered yet another ressource. Then have a random creatures or a trolling MMO player come to destroy it, then start over. Kill 100 slimes to gather some lenses, then build a new weapon that will break after you used it 6 times. Even when the setting seems nice, it just remove most of the game interest. Most of the people here have work or studies. We don't need more busy work when we are back at home. Better be immersed in a engaging story, face new challenge or have fun. I don't see any fun, challenge or mind involvement in making another pickaxe and use it on another carry.
