Minecraft is an easy pick, it's such a classic. So many possibilities and endless gameplay for you to spend hours and hours on. There's survival and hardcore for those who like a challenge, and creative for avid builders and players that just want to relax and let their ideas flow. Even if you aren't too into vanilla Minecraft, there are millions of modpacks available to mix it up a bit, and texture packs also exist for those who think the looks are a bit too bland.
