I think recommending this is akin to randomly shouting in public, "FOR THE LOVE OF GOD, DON'T PEE ON THE SEAT!" - Everyone who has half a brain already knows this, and anyone else just won't get it. :p
FTL is a must-play game. End of story. But in all liklihood, you've already played it.
Wher Machinarium had its share of 'slightly too difficult' puzzles (but an in-game walkthrough), Botanicula has fewer, but leaves you on your own to figure them out anyway.
That, however, is about the only negative thing I could say about this otherwise fantastic game. Clocking in at around 3 hours, this won't eat up a huge chunk of your life, and the level of interactivity is frequently impressive and delightful. Perhaps the greatest of its assets is a phenominal use of sound, putting it above and beyond similar games as it creates its own truly unique atmosphere.
Not entirely a game, and not at all for everyone, I suspect many would feel they had wasted their money after playing through Dinner Date. The closest game I could relate it to is Windowsil, however even that isn't fair. Both are interactive, but Dinner Date does not require the player to solve any puzzle. It is a story, told well, and relatable, that requires only the player's input to progress. However it does mainatain a level of interactivity, and, in my opinion, it is an experience worth having.
