Name any really good game

Do expansion packs count as sequels?

Armed and Dangerous. Short, 3rd-person shooter, hilarious. Get it for the humor, not the graphics (not too good) nor the gameplay (OK). It is funny.

Eternal Darkness.

It may be premature, but I would also mention Vampire Bloodlines - absolutely outstanding game, unlikely to get a sequel because it bankrupted the company that made it.

That was definitely an outstanding game as well. I havent felt that level of immersion in a game since. The haunted hotel area freaked me out the first time through.

Alpha Centuri.

Can't really think of anything good without sequels.

"When NASA first started sending up astronauts, they quickly discovered that ball-point pens would not work in zero gravity. To combat this problem, NASA scientists spent a decade and $12 billion developing a pen that writes in zero gravity, upside down, on almost any surface including glass and at temperatures ranging from below freezing to over 300 C.

The Russians used a pencil."

I hate to go off-topic, but Zalmoxis, are you Russian? Because that is why I love Russia.

The haunted hotel area freaked me out the first time through.

Me too. I literally felt a tingle down my spine and I clearly remember thinking, 'Wow, it isn't just a cliche!' I loitered in some of the rooms, just to savour the feeling. And the basement, with that boiler room! Awesome!

Somebody must own the rights to the game, now, even if it is just a creditor. It would be madness for them not to do something with it, IMHO.

Strife! It's a game from 1996 and truly an amazing game for it's time!
It's an action/rpg with an excellent story and gameplay (I.M.O.)! You can for example use a certain device which when deployed acts as a teleporter through which allied soldiers/rebels come and aid you in battle. I thought that was great! The voice acting is also done really good! It's a shooter unlike any I have ever played till this day, non seem to be able to compete with it. Ah.. the nostalgia just thinking about it!

[Mount Suribachi]

Alpha Centuri.

Don't think that counts, its just another Civ game by Firaxis, but set in space

(btw when I say "just", I'm not dissing the game, its one of my favourites of all time)

Sacrifice. Brilliant game, one of my all time favorites. Awesome music, great sense of (nasty)humour, challenging gameplay, AMAZING graphics.
