What was wrong with ACIV port? It played just as good as any other system (minus the visuals of PS4/ONE for obvious reasons).
The only reason you think Nintendo games are worth more is cause they never discount. If Nintendo discounted games months after release you would have the same perception.
Look at the mobile market. People have been conditioned with free and $1 games that anything over $5 seems expensive. Game may be 10x better but that audience is expecting $1 or less otherwise its overpriced.
