This 
is not going to be a review of sorts: However, I bought ‘Legend of Grimrock’ (producer) the other day, which is an old-style hack-and-slash dungeon crawler a la “Dungeon Master”, or, rather, more to my experience, “Eye of the Beholder”. I’ve only briefly mentioned “Eye of the Beholder” before on this site (here).
The game has been a resounding success, if I may say so: It looks like the Finnish developer has already recovered the cost of producing the game. This is surprising: Back when I played EOB (and EOB2) I always thought the introduction of games from Id Software (you know the 3D FPS) basically replaced the trusty dungeon crawlers: from one day to the other, these crawlers became ‘out of date’ technology. No matter how you turn it: Quake, was the turning point for PC-gaming.
While playing Grimrock, I run into frustrations as reported by many others on the Internets: however, most of them are actually neglectable if you think about the type of game Grimrock actually is: It’s a dungeon crawler. You’re supposed to take the time for it. For someone who finished both EOBs, like ages ago, the puzzles are what make these kind of games enjoyable.
