The same thing is happening to me. I have nearly 30 games that I haven't completed and the list is growing thanks to my PS plus subscription.

Yeah, before ps+ I would playthrough a game normally and then go online and look at trophy guides to clean up. Now, I think I'm going to read trophy guides before to obtain the most in a single player through. If any game requires something like, oh I don't know, 10,000 online kills I'll just pass and move to the next game.

Heres my backlog for PS3...

I want to finish over half of the ones I've started, and atleast try ~20 of the ones I havent started yet.

If you are a trophy hunter I know GoW and Jak will be easy to plat. Puppeteer would have been easy if I read the guide first. And SotC is broken. The made one of the Colossus too hard that you can't beat it under a certain time to platinum. And you have a lot of the same games i do.

Well, just don't play every game just because you can. When I buy a Humble Bundle because I'm interested in one game for the whole bundle I will surely not play the other 5 games just because I could and even if I like to get the achievements or badges. Or even worse, Just imagine you would start to watch every movie or show you get with a TV subscription like with Netflix just because you don't have to pay extra for these "free" movies in the subscription.

Achievements and Trophies are nice and all but to play every game you can just to get more? Damn...

yeah, i do that too.  i glance at the trophy list and if i see something impossible on the list (or something just not worth my time) i say "fuck it" to the plat before starting the game.  multiplayer based trophies are typically impossible for me.  anything that is just pure grind is just not worth my time,.. i have too many games to play games in a way that isn't fun.  things like bolt collector in R&C (collect 1M bolts and keep in mind the ryno cost 150k) can just go fuck itself.  that's like 5 extra playthoughs after doing at least 2 full playthoughs to get the gadgeteer trophy.

yeah,.. i'm surprisingly okay with finishing a game with "only" 80% completion these days.

I have this exact same problem....well dilemma. I just made a chart 2 days ago about how I would finish my games to plat. It certainly is a long one and will take probably over a year to complete entirely. You gotta love and hate plus at the same time. Hahaha

yh, im in the vgchartz trophy league too :)

I heard about GoW and Jak being easy, but not a huge fan of those so they are lower priority. Its so tempting to load up the other games, but at the same time I want to finish the games I've already started. My completion rate is only ~62%.

thought if you didn't renew the games become unavailable......

I'm actually having the same issue wiith games with gold........on the 360 side noot the one though......but that might be because I don't really play that often, an 8 hour game can take me over a month to complete.

The games are unavailable if you don't renew. However, it's just saying that if you do renew, the games that you previously downloaded will still be available .

I love the fact that I can erase a game and revisit the game through my download list and it never goes aways as long as I have my plus activated.
