Hi Louis, both of those games are great. Broken Sword 5 has gameplay more along the lines of 1 and 2. It has beautiful graphics, a great storyline, good puzzles, and it's just a lot of fun to play. I do think it's very convenient that George and Nico just happen to run into so many familiar faces when they travel the world, but then again, that's part of the charm of these games.
The fifth game is my second favorite in the series after the first.
Life is Strange is fantastic so far, especially if you like story driven exploration games. The main character discovers she has the power to rewind time, which is both an interesting premise and a fun game mechanic. There are a lot of optional things to explore and optional character interactions which add to the world the main character, Max, inhabits. It reminds me somewhat of Dreamfall Chapters in that respect, which is another game I recommend if you like The Longest Journey series. Episode 1 of that game is already out, and episode 2 should be out next Tuesday. There are optional dialogues you can have in that game that I think a lot of players miss, and a lot of exploration, especially in Europolis. That area is huge. Both of these games are my current favorite releases.
If you liked The Book of Unwritten Tales, I highly recommend its sequel. Great characters, a nice long gaming experience, and it's incredibly funny and fun. If you haven't played the original and like the look of its style, I highly recommend starting with the first game, then the Critter Chronicles and finally The Book of Unwritten Tales 2.
