I have played a bunch of the games listed already so found some other ones on my steam list:

UnEpic was fun, I'm about half way through but haven't finished it but I had to stop playing games for the most part recently.
Not sure if it really fits but Toki Tori 2+ was great. I loved the way it taught you mechanics and the songs needed to progress and travel in the game because it is gated by knowledge of the game. You can do everything but warp right from the start of a playthrough.

I am looking forward to Ghost Song, it looks amazing, and I hope Chasm turns out well as it has been around for a while but not released.

I don't spend a lot of time on many gaming websites but I've been using and contributing to IGDB way more then I expected. They are still building the site and have started getting voice actors to create pages.

I really like seeing the site get improved and being able to take part in that so I end up there a lot.

I have a ton of games I feel like going back to but I don't have the time or I still remember how to do almost everything so am putting them off for now.

The ones I can think of right now are:
-Shadowrun (snes), the keywords system and npc tricks in-game blew me away when I was a kid. Played through it a year or 2 ago (4th time) so it will be awhile before I play it again
-Metal Warrior, loved trying to beat this when I was younger. Didn't realize I had gotten to the last level till I beat it years later
-Beyond good and evil, played it to death before I lost my copy
-The World Ends With You, will be playing this again later this year
-Hybrid Heaven, putting it off because I don't think it held up that well and lost my copy

I want to replay almost ever game I enjoyed years ago just to see if they are still good now lol.

A game that I would give up playing any other game shown at E3 for?
I have to pick The Legend of Zelda: Breath of the Wild over anything else because it is a series I have played forever and they have managed to create, what appears to be, a gigantic and interesting world to explore. I don't think I will have time to play anything else for quite a while if I get it anyway.

The next closest game that fits for me is Persona 5. I haven't played the other games in the persona series but I have heard enough to get me excited for this one. I have played Shin Megami Tensei games before and I am looking forward to Apocalypse as well.

And, because I feel like adding some more titles, The Turing Test, Manifold Garden, For Honor, and Gwent also caught my attention.
