So Many Games I Haven't Finished or Even Played. I Could Use Some Help/Advice

Half-Life, Portal, Resident Evil 4, those would be mmy top 3, I've played a bit of JC2, Darksiders and Fallout: NV but didn't get too far, got bored, haven't played Skyrim, not really my kind of game.

Half-Life and Portal are both short and brilliant, best quality to time ratio you could find :)

You can beat Portal the day you start it and it's a great game, if you want to start tackling your backlog I would suggest that one.
Of the ones I played I can also recomend JC2 and RE4, Skyrim however was a big dissapointment to me.

It just so happens that SG gave birth to a group just for you!

(And yeah, Portal is super fun and quick to finish!)

New Vegas, although you won't be finishing it anytime soon.

start with portal, it's super short.

then maybe go for half-life or fallout new vegas, depending on how much time you wanna invest, ~10 hours or 150+ xD

I recommend The Elder Scrolls V or Fallout, it will cost most time.
if you don't want cost too many time , maybe try portal.

Portal - just so you get quickly get another finished game. after that, skyrim - duh!

As someone who's been working on this problem for just over two years now and is almost done trying everything, I can tell you what I did.

First off, forget about beating everything. There's probably a ton of crap that you've picked up over time that's not worth playing. The problem is figuring out what's worth your time. I started sorting my games into categories based on how much I wanted to finish them. For me, I just went with "Favorites", "Mediocre", and "Ignore", where favorites is "will play more", mediocre is "might play more", and ignore is "never again". You might want more categories, or you might just want to go down to yes and no. That's up to you, but come up with a system and sort the games you've started already.

Second, figure out how much you're willing to do. Once you're done sorting the ones you've already played, you'll probably have a good chunk of games that you've never touched and have no idea about. Figure out how often you want to commit to trying a new game and then calculate how long it'll take you to finish. In my case, I decided that I was willing to try two a day and came up with about two and a half years at that rate (~1800 games, I'll save you the math). That sounded fine to me, so I ran with it. You might want to go one a day, or three a week, or whatever. If you decide to do some extras, great, but stick to the schedule.

Third, make sure you don't grow your backlog while you're working it down. If you buy a new game, try it immediately and don't count it toward your regular goal. Or if you don't want to play it, play an extra game out of your backlog instead. The goal here is that if you buy a bundle and add 8 more games, you're going to play 8 extra games in the next few days to make up for it. This will also help you cut down on the excess purchases - if it immediately makes more effort for you, it'll have to be something you really want.

Fourth, reward yourself when you actually finish a game. Count it as a day or two off, maybe longer if it's a particularly long game. That way you have some incentive to actually enjoy some of the stuff you like, instead of feeling forced to play Brilliant Bob today to make progress.

And finally, realize that it's going to be work. You're going to play some garbage. You're going to have days where you don't want to do it. Do it anyway, or if you really can't, make it up the next day. There are people on Twitch who make a living off playing and beating every game on a specific game console. That's their job, and sometimes they're miserable during it. Clearing a backlog is legitimately work, and you need to treat it as such. If you want your games to be fun, give up on the backlog.

As for a starting game, I am going to recommend that you ignore the list you put in the poll there and tell you to play Heaven Forest NIGHTS. Why? Because it's terrible. It's one of the worst games in your backlog, it's reasonably short, and it'll mentally prepare you for going through the rest of your games if you're actually going to do it.

This really is an amazing time to be a gamer.
I spent my childhood playing the same handful of games over and over because that's all I had. I guess I finished Deus Ex a hundred times.
Now in 2 weeks on Steam I have 200 games I want to play, and little-to-no time to play them. It's awesome.

I'm going through Half Life right now and it really is as good as they say. I'm a little halfway through in around 9h, and I play FPSs pretty slowly, so it should take around 15h to me and 12h to someone who plays faster.

New Vegas and Skyrim are great, but you won't really play anything else for a good while once you start them.

Haven't played anything else on this list yet.

Portal is fairly short and enjoyable so its a good place to start

I just recently bought Portal and need to get to it myself, so that has my vote

HL, HL2, HL2:Ep1, HL2:Ep2
Portal, Portal 2
