Steam's recommendation algorithm is trash

Look, I know that writing an effective recommendation algorithm is difficult.  That's why, back in 2009, Netflix offered a $1 million dollar reward for improving the algorithm by 10%.  But, really Steam, if I've played the first game for hours, surely there's a higher than average chance that I'll be interested in the sequel?  How have I not played anything similar in the past?  I played the first game!  The gameplay - having played the demo - keeps all the good bits!  Sure, some sequels - like Anodyne 2 - take a totally different approach to the gameplay, which I don't think I'll enjoy, but I'd still like you to acknowledge that I've played the first game and that I might like to know a sequel exists.

I made a tracker of how much I spent on my steam games and how much I've played them...

...and the results are a little embarrassing.  I knew I owned a lot of games I hadn't played - hence my new year's resolution to play some of them - but I didn't realise quite how bad it was.  Of the 188 games I own, I've completed around 29%, or 54 of them.  23%, or 44, I've played a little of, as in, I've at least downloaded and opened the game.  48%, or 90, I've literally never opened.  So, yeah, I should probably stop buying games.  I've also spent £949.88 since 2013, and played for 3,548 total hours.  That does mean the total cost over total hours of playing is 27p - which isn't terrible - but the mean cost is actually £3.14 per hour, which is.

Over the past few weeks, I've mostly been working on my final year lab report - which is worth 16% of my total grade over the four years, and so effectively decides my degree classification - but I have also been playing some games.  I finished Idle Evolution, a cute little game based around the periodic table.  You unlock extractors which extract atoms, and you spend those atoms on further upgrades, basically playing through the history of the universe and life on earth.  Unlike other idle games, there's no resetting for an increased overall bonus, and you can finish the whole thing in 24 hours (according to the steam achievement) if you keep the game active.  Annoyingly, that means in the foreground, not just open.  When it considers itself closed - either literally or in the background - the number of atoms drops drastically, and, even if it didn't, you can't store enough atoms to bother leaving it alone for too long.  It was a fun way of becoming comfortable with the periodic table.  I needed some chemistry to begin my degree (genetics), and some was required in first year, and I'd say that's about the level this game is - pre- or early university.

I also played an actual educational game, The King's Request.  That was a really fun little game - took me about half an hour, though I did replay the last half of the game to make sure I hadn't missed anything - and it was free.  To defeat enemies, you need to answer a quick question about their physiology.  There are a maximum of four answers and no penalties for getting it wrong, so you could just guess your way through.  It's really well put together, as a game, and I enjoyed playing it, despite my anatomy being less than my chemistry (some pre-uni and an optional module in first year, so theoretically the same, but I've needed to recall the knowledge less since).

I also completed Dark Parables: Curse of Briar Rose because I (correctly) predicted that it was short enough to play in one sitting.  I really enjoyed it.  I'm normally bad at point-and-click games, but this was at just the right level of mystery for me.  That said, my previous experience was in playing the Discworld 1 and 2, which are notoriously difficult, so maybe I'm not so bad.  Through I struggled with (and gave up on) Deponia, so...

Oh, I did finally complete the first Discworld game!  It's available for free online.  I followed a guide.

One of the issues I've been having with games - apart from being a compulsive buyer - is that I really like long, involved RPGs but, since starting my degree, I've not had the brain power free to focus on them.  I've replayed some that I'd finished before - FFX and X-2, FFIX, FFVIII, etc - but a lot of the time, I'd buy them, play for a little while, and then realise I didn't have the energy to focus on it long term.  That's why I didn't finish Alphadia Genesis before challenging myself to play all my games this year.  I'm still playing through the Phoenix Wright Trilogy, and I really like it's episodic nature, for reasons of following the plot.

Oh, I'm still playing my sims game, though slowly.  Since the christmas sale, I now own all of the DLC, so my total price for the Sims 3 is £190.50.  I have played it for 390 hours though, so my price per hour is 49p, and that will drop further over time.  So it's fine!  Oh, theoretically, I'm still playing the Banner Saga, but I've not opened it in a while.  I'm also replaying Anodyne just because I felt like it (but not enough to buy the sequel).
