Basically, it's X-Com: Terror from the Deep with more interesting story mode and good horror atmosphere. Combat and base management are simple, but solid. Not a stellar game, but if you like old-school turn-based games or want something in an unusual setting - give it a try. Just remember - in it's current version the game needs polish.
This is a good game. It could be great, but there is one "but". You can heal your Daughters only by sacrificing other Daughters, and all these Daughters should be approximately equal in level. At the beginning of the game, this is not particularly annoying, but closer to the end ... Another unpleasant moment - you cannot retreat from the battle with the boss. And if you lose it, then ALL your Daughters will be destroyed and the cycle of struggle will start from scratch (well, not entirely from scratch, but it takes a long time to explain). In short, this is NOT a game for everyone.
Once again there is no mention of time limit in this game on the main page. If you want to experience slow stategic gameplay - forget about it. This game is all about "tension" (aka masochism) - you have LIMITED time to finish your missions, which forces you to hurry, to engage enemies head-on, leaving no place for subtle approach. Some people love it this way, some hate it this way. Make your choice of buying this XCOM wisely.
Let's immediately put all the dots above "i" - this is not Fallout. This is a game "inspired by" Fallout. It has many shortcomings - not the best optimization, very unfair difficulty curve of combat, the constant need for micromanagement of resources, a lot of backtracking. But this game has an undeniable advantage - the atmosphere. This game feels old-school and if you want "the spirit of that era of the late 1990s" - then you should try this game. However, be prepared for the roughness of the gameplay and cumbersome interface. In other words, this is a niche game specifically suited for GOG's core playerbase. Insomnia: The Ark plays like a remnant of another time and for someone it will be deal-stopper, for others - quite the opposite. For me personally it's solid 4 of 5, but - it's me. Your opinion may wary.
It been 27 years and yet - this still IS one of the best horror games on PC. ...Get ready to enter the inheritance rights of the old mansion, which once served as a family nest of very powerful people, then a hospital for the insane ... Now, however, this house has become the gateway to the Other Worlds, and the Forgotten, but not weakened at all, Ancient Horrors are ready infiltrate our world. Get ready to meet their servants face to face - but remember: some Creatures cannot be killed by mortal weapons and only your mind can defeat them - IF you guess how. Nevertheless, you will also have to work with your hands - you have a whole arsenal at your disposal, starting from a broken bottle and ending with a chainsaw (to which you have to look for gasoline). Do not forget to add to this list several playable characters, a rather cumbersome skill system (which, of course, can be developed), usable and powerfull magic, a clever plot, non-trivial boss fights - and, of course, terrible screams that your character will make when he/she stumbles upon creatures of darkness. The disadvantages of the game are understandable - long-outdated graphics, slow gameplay, uncomfortable controls, some audio bugs and, of course, the very tests for your mind that I mentioned above. Nevertheless, this is a unique and still largely unsurpassed game. Play The Legacy - you will not regret the experience.
There is one feature of this game that is not mentioned in official description - you have limited time (about 30inutes) to complete each mission. At least in the existing build. So if you want a game with thorough and unhurried exploration of the territory - do not buy it, at least for now.
