First I thought I have no idea which game it could be, but I'm intrigued after this description. Than a thought occured. Could it be...? I looked at youtube for the trailer of what I thought about, and indeed, there was a dangling lamp. Resident Evil Revelations. I played the crap out of this game.

Command & Conquer: Red Alert 2
(Change YoY: -3)

My favourite RTS franchise of all time is Command & Conquer, and the best game in the series in my opinion is Red Alert 2. It's not the highest ranked game from the series in my top 50, but a lot of that comes down to nostalgia for the other game that's still to come. I've always loved the fact that while other RTS games were constantly trying to change things up in order to modernize the genre, C&C has for the most part remained very traditional. Naturally the series has changed things up and updated its gameplay mechanics, but the core of the franchise for the most part always stayed the same. To me, this was the game where they found the perfect balance with this.

The gameplay was smoother and more varied than before, but still contained within it the basic gameplay loop that the first game in the series established half-a-decade earlier. Let other franchises worry about modernizing the genre. C&C has always been at its best when it doesn't try to change the formula too much. There's a reason why the lowest point of the series to this day is Command & Conquer 4: Tiberian Twilight. 

Yes! Very good.

Correct, your boyfriend has a good taste. ;)

As I said before with other games, I love adventures. And this game is another one, a small but heartwarming adventure. You play a little kid in Japan in the 70s, as the monster movies became big. The kids roam around and do stuff, and you playing one of these kids has to solve quests to progress the story. There is really not much to it, but it all is so masterfully executed, it just clicks.

The game was part of the guild-series. That was an experiment from Level-5 to ask different well known game designers to go crazy and implement an idea they always wanted to do, although on a small scale. These guild games were published by Level-5 on the 3DS eShop as download games. And actually I liked most of these guild games. I wish Level-5 (or whoever) tries again something like this, it showed some interesting ideas in result.
