This is an interesting subject.
What are some games from this gen that will be rare in the future?
JRPGs tend to age better than other genres which can explain why they are usually the rarest games when you look at previous gens.
Also, exclusive games tend to be more rare.
Most of the times, rare games need to be well received by critics but not too well received otherwise it will sell well and if it sells well it dampens it's chances of being rare as more people own it making it more available to buy on ebay for example. It's usually the games that scores in the 75-85 range on metacritic.
Games with great art style have more chances since they age better.
A game needs to have some kind of legacy for it be remembered and thus required.
So with all that in mind, one would have to think of games like Lost Odyssey, Tales of Vesperia or Valkyria Chronicles.
Blazblue because of it's low sells, great gameplay and good art style.
The Yakuza games? Perhaps.
No need to mention Nintendo's first-party games. Even though they sell well they always tend to become rare.
So what's your opinion about all this?
