First one is a PC RPG/platformer, circa EGA/386 era (early 90s). 4 small, square looking heroes that all follow in the footsteps of the leader, 2 shoot projectiles in mad spam mode, 2 are useless. They take missions/quests which are 2D side-scrolling, platforming levels. They only level up once in the game, and when they do, their stats drop briefly, then keep rising.

Odd quirk: The wizard and ranger had ranged attacks that were 95% of your DPS. The fighter and dwarf(?) only swung these useless 5-pixel swords.

The only mission I remember: Go to the elven town and save them from rampaging silkworm caterpillars. "Screenshot":

Second one is for Sinclair Spectrum, crica late 80s. I had a Spectrum+ so it's not a 128 only game. I couldn't figure out anything to do in it other than walk around and eventually get in an ice cream truck looking van. At some point a blimp would show up from the left, and later my character would spontaneously die. Maybe the zeppelin would drop a bomb on you? I never figured out anything about what to do in it. There were no obvious things to collect, or any way to earn points (that I saw). "Screenshot":

These are rather obscure games. I can't google anything for the first, and I've actually been going through Sinclair screenshots alphabetically with no luck.
