<span class="bold"><i>Discovery: In the Steps of Columbus</i></span> Despite being an Impressions game, I've never heard anyone else talk about this game. It was probably objectively not very good (even for its time), but I it was one of my earliest (full) computer games that I got into after my family got a computer.
This one would seem to be legitimately obscure, too:
there are only nine votes for it on the Community Wishlist, and zero comments. :(
<span class="bold"><i>Culdcept</i></span> A CCG/board game stuffed with awful JRPG/manga cliches; I've only played the (poorly) localized PS2 port of
Culdcept II. This is seriously one of my favorite games of all time (for the gameplay, obviously :P ).
One of those cases of "far more popular in its home country [Japan, in this case] than elsewhere" -- there have been at least three video games in the series (not counting expansions/ports/remakes), as well as a manga series, but only two games to date have been released in North America (or anywhere outside Japan, AFAICT); according to the page linked above, the latest new game in the series (a 3DS original, apparently, rather than another revised and expanded port) will come to N.A. & Europe later this year.
If I hadn't happened upon a single, little-played rental copy of the PS2
Culdcept years ago (which I purchased several years later when the rental place started selling off some of their PS2 games), I likely wouldn't know of the existence of these games at all.

Ragnarok[/url]
A Norse-mythology-themed,
NetHack-inspired roguelike from well before the term "roguelike" was in common use. Along with
Castle of the Winds (which, interestingly, seems to be remembered by many more people than this game is), this was my introduction to what I would later come to know as the roguelike (sub?)genre.
Ragnarok's a little clunky, and not open source (so it still requires a DOS environment), but it had a mouse-driven GUI, which was novel for roguelikes at that time (especially DOS-based ones), and made it a bit more accessible for a noob, even if I wound up using the keyboard for most things eventually.
It's freeware now, though I kind of prefer the slightly older shareware version, since an annoying (read: deceptively dangerous) new creature was apparently added later that makes playing the last version more vexing than it already was.
There was also some little shareware turn-based hotseat-multiplayer (only -- no AI opponents) tactical battle arena game where each player controlled a wizard who could mainly summon creatures; last wizard standing was the victor. Sadly, having no friends willing to play what was, by the time I discovered it, already a several-years-old game, I only ever played the thing against myself. =(
This was some little one-man affair, too: no music, no sound card support (I think there were some minimal PC speaker sound effects), very simple graphics. I want to say it was actually
called "Arena", but, as one might imagine, searching the Internet for things like "Arena DOS game" doesn't give the results I'm looking for. ;P
