That’s a surprisingly difficult question. Everyone has different interests, so it’s hard to make a catch-all recommendation.

With that being said, I’ll go with Chrono Trigger. It’s a true classic with interesting characters, a solid enough story (that doesn’t outstay its welcome), easily approachable gameplay, and an amazing soundtrack. It easily ranks among my favorite games of all time.

There may be some impact, come July, when the third party apps stop working. However, I have to imagine that the vast majority of mobile users use the official app. Quality may take a hit, with the loss of some mods and mod tools, but Reddit will be just fine. Sadly, Reddit rates too highly on content, users, and resultant utility (for many communities) for most users to completely abandon it.
