TL;DR this Bundle is good.

I had all the games before except Splice and Waking Mars. My opinion on each, since I like ranting for no apparent reason, especially about game design:

Splice is a really bizarre puzzle game, where the rules aren't explained at all and you're left trying to figure everything out on your own. While I generally advocate this sort of game design over overexplaining overcomplicated controls, a few pointers would have been nice, as I had to exit the game and restart it just so I could figure out the controls. The puzzles also grow gruesomely complex in a very short amount of time, which would be fine except there's generally only one solution to each puzzle. For most of my 30 minutes of my playtime so far, I was clicking around, wondering what the flip I was doing and how the flip I was managing to solve puzzles while having no idea what I was doing. Not how I generally like solving puzzle games.
That being said, everything else about the game is perfect. It's beautiful, the music and graphics are lovely, and the rewind/fast forward moves feature is really well made.

Waking Mars is also a really beautiful game. A bit dialogue-heavy for my taste, but that's just personal preference. The voice acting was decent overall. I really liked the idea of wandering around through cave systems and planting seeds for peaceful alien plants and animals. For the most part, it was all just dodging stationary enemies-- basic platforming stuff. Then the game introduced a moving enemy, which was cool and all that, so I entered the next room... and it was a horribly-designed twisty corridor with about twenty of them. No spaces between them to pause, no way to distract all of them, very low HP, so only a few hits would kill you... I basically ragequit in that chamber. Up to that point, though, it had been a fairly awesome, balanced, well-designed game, so it was strange. I think that was about an hour into the game; it was really good up until that point.

I generally can tell how much I like a game by how long I play it. If it's fantastic (World of Goo, Little Inferno, King's Bounty, Bastion, VVVVVV, etc), I play it for hours, and come back to it again and again. If it's good (Like the games in this bundle), I play it for half an hour to a few hours, and sometimes play for a few sessions. If it's horrible (Fieldrunners, Blueberry Garden, Brainpipe, Snuggle Truck, Spirits, the list goes on), I only play it for a few minutes, then close the game and never play it again. My playtime for the games in this Bundle is medium to high, so I'd say it's a pretty good Bundle. I think I just have too many games at this point, and I'm getting cynical of the ones I have.

As for Machinarium, it's up there in the "fantastic" playtime area. I also dislike point-and-clicks in general, and I stink at most of them, so I ended up following a walkthrough for this one for most of it, but it's amazing. TotalBiscuit made a review of it here that's worth watching.

NO MORE STUPID MEME JOKES?! (wait, what is Meme?)
