there are plenty of BAD video games. They are the ones with bugs, functionality issues. Many are alphas or betas that never become polished enough for a final version, but have taken tons of money in for "development" An example is infestation (formerly WarZ) that never lived up to the hype it brought and much of its promises to players were not delivered. Another was DayZ, which still might be indevelopment? It originally came from an Arma 2 mod, which actually was better than the standalone game itself. Those are the games that are really terrible.
While there are a lot of bad alphas (many found on steam), there are plenty of great ones! ARK:survival evovled for example, was in alpha for almost two years before being finished, but the dev team continuously updated, fixed, and added content.. as they should be doing to make the game better. Another great game is PubG, mostly living up to expecatations.
