For those who remember the 16bit era of gaming, there's a Port/Remake of one of the first isometric action RPGs, The Immortal over on Steam. However, even though it's on sale, it's even cheaper on GOG by about half. Since I can't find a trailer quickly, there's this:

• 3-D Adventure like you've never seen!
• Fully animated creatures and deaths - watch out or you'll be spiked, slimed, or eaten by giant worms.
• Fight trolls, spiders, and goblins in live action battles.
• Discover the powerful secrets of arcane objects. Use them correctly or perish.
• Unleash magical powers to fly, shrink, and change form.
• Eight levels of challenging puzzles to solve and over 50 chambers to explore.

I remember this game when it came out. I snagged it and it was probably one of the more frustratingly difficult games when I was a kid. Now the frustration can be yours!
