Love that game, as well. It was the game I bought with my PS2, since I was a fan of From before it was cool. Mainly the King's Field series. Did you by chance buy the converted to PS4 version that they released a year or so ago?

@ OP

I really enjoyed Kingsley's Adventure on PS1. It was a simple adventure game, but was enjoyable. I'd love to see a remake of that game, only with an expanded world. Rascal was another one I loved playing.

No, simply because my PS2 is still functional and I have my original copy with me XD

Yeah it's definitely one of the scariest games I've ever played. It's such a shame it didn't release in NA as it really did deserve to reach a wider audience.

Alien Front Online for Dreamcast. Third time I've mentioned it today.

I had some fun online earlier with other DC games, but Alien Front Online kicked things into overdrive. It was a simple 4v4 vehicular combat shooter. It also had a fun arcade mode with a high score leaderboard, on which I was ranked #1! I was a top dog in the online as well. This game is where I began using the name COKTOE, although I spelled it COCKTOE at the time. The game came bundled with a mic that allowed limited voice chat. An insanely fun new toy that I fully abused.

I adopted the persona of a German man who was often concerned with getting c*m stains out of vinyl, and always inquiring about what might be the best method of removing said c*m stains from said vinyl. I ran with this bit for A WHILE.

The whole thing was a super-fun new experience.

Henry Hatsworth and the Puzzling Adventure!

It's a silly game with a serious mix of platformer and puzzle. It was on the DS and the top screen was the side scrolling level that you had to jump, climb and shoot your way through. However, defeated enemies fell to the bottom screen where a constantly rising tide of colored blocks threatened to rise to the top. You had to switch periodically to the bottom screen and clear the blocks or the defeated enemies would return and attack you like the evil sun from Super Mario. The plot was as goofy as they come, all about gathering the outfit of the 'Perfect Gentleman' and the text was vocalized as Mario-like noises, but based on English accents and occasional British-isms like 'tally-ho!' or 'Guverner!' instead of an Italian flavor. The bosses are all unique not just in the top screen, but in how they affect your puzzle screen below as well.

It's a bit short at 10-ish hour on a basic playthrough, but all-in-all a solid mix of two genres I love.

Another one that's hardly talked about, (it did get a little attention back when it released but was very quickly swallowed by the mists of time and sold very little) is Silent Hill Shattered Memories for the Wii. It made some of the best use of the hardware of any game I can think of with its intelligent user of motion and pointer controls and (for the hardware) beautiful visuals, and the cryptic story kept me guessing. 

Medal of Honor Heroes 2 was also a cool little Wii game with awesome pointer + motion controls that's been pretty much entirely forgotten.

Space Station Silicon Valley on the N64. Easily my most enjoyed obscure game. No one ever talks about it and it's such an underrated gem! It could be a glitchy mess at times and the graphics weren't great (even then!) but the whole concept and humour of the game more than made up for its flaws. For anyone who doesn't know the game it takes place on this space station inhabited by mechanical animals and you control a robot computer chip that can only survive by taking over these mechanical animals. Every level is mission based and you have to complete the bizarre objectives (plus bonus extras) to make it to the next level. Every animal has its own abilities/ways of moving around which makes for some creative puzzles, platforming and even combat. I think of it like a sort of pre-cursor to Super Mario Odyssey where cappy controls other beings but instead of this being a fun extra in Mario it's an absolute necessity in Silicon Valley. Worth a pickup for anyone who owns an N64!

this one:  SnakeRattle N'Roll   (nes + megadrive)

You play as Rattle or Roll (a red or blue snake), and run around in these 3D isometric levels, collecting these balls? (best to match the colours to the snake colours), to grow until you can ring a bell, that then opens up a path out, leading to the next level.

(nes version above, not as good looking as the megadrive one)

^ mega drive version.

Anyways the music was crazy good for its time, and it was fun platforming around as a snake.
This was made by Rare, waaay back in the day (1990 release) and its probably not that well known, even though reviewers had very high opinions on it.

Still have my copy on the attic somewhere (NES).

Superb game but I’ve never finished it. I always got to one of the ice levels (9 or 10?) and could never clear it, insanley difficult. Maybe I should fire up my NES and give it a spin again, it’s at least 20 years since I last played it.

Im not *sure we ever beat it either.
As kids we would play together as a group infront of a tv, and take turns.... we used to love this though.
