Ancient Enemy is one of those card games that abstract a journey of discovery and battle. You charge your magic by playing Solitaire "combos", then fire at the enemy. The choices you make on your journey don't matter at all, they are just levels to pass through that barely differ from each other. That's the entire game!
So why did I play it? Well, because the sound and the texts that my character was "saying" were intriguing. Ironically enough, the game had a "Skip story" button, when in fact that was the only thing that interested me - I wanted a "Skip game" button. Alas, the end of the journey was a complete let down, with a generic enemy that presented no challenge and a blunt and uninspired story ending.
Honestly, when I was playing it I thought: anybody can make games and sell them if this is a Steam game that people pay money for. Just look at the official site of this 2018 game: it looks like it was made in 2000.
