@amigalove i think the first one is The Immortal, god I hated that game for its difficulty... the second ine is easy! That's the cover pic of Pool of Radiance. The third one looks like another of the SSI games, but I cannot say for sure... the last one I don't have a clue, but it looks gorgeous :)
@amigalove yes*! After the outro there's a note saying how long it took you (in game days) and asking you to send a letter to Lord British sharing your accomplishment.

@amigalove last year october i quit my job, and the first game i played with my now ample spare time was ultima VI (the gog version), 30 years after I bought it (still have my notes and the high-quality paper map from back then).
