For me it’s Chrono Trigger. I always want to play it. I want to show it to my children. I hope it will be regarded as a masterpiece for generations to come.
There’s a game called Heroes Hour on steam that is like the pixel version of an expanded HoMM3, the over world and town building and unit recruiting is all almost the same, but the fights are real-time auto-battler that you can pause to cast spells or give directions to units. Really scratches the itch left by HoMM3
