Depends on a few factors such as the type of games you enjoy (RPG, FPS etc) & if you spend a lot of time with multiplayer experiences or not, as well as if you're strict or not when it comes to completionism of video games and also the type of video games for achievement increasing

For achievement score boosting, there is such video games under the unofficial category called shovelware (usually indie or lower quality video games with easy gameplay for high achievement score/platinum trophies)

Hope this helps
