I play a bunch of different games all the time, and usually on different platforms. The last completed game was Spear of Destiny - the 1992 Wolfenstein 3D standalone expansion (and prequel) - the GOG version.
At the moment I am playing Nurse Love Addiction; a multiple pathway/ending visual novel from 2015 made by Kogado, a Japanese studio who made maes for MSX, MSX 2, Playstation 2 and PC which I am playing it on. I still have quite a long way to finish the game as I am only about 1/3-1/2 way in based on the 13-24 hours playtime! I hope to complete it this year (a little hard with a one year old baby who don't sleep well), so I perhaps can manage a few other games before the new year.
I usually have two lists of 13 games each where I plan (but usually fail) to beat at least 10 on each list, this year the secondary list have been dedicated to games I've started but haven't completed, where both Spear of Destiny and Nurse Love Addiction was on - Spear of Destiny was a complete restart however, where Nurse Love Addiction is a continuation of my old save game.
Next year's primary list will be same style as this year; to work on the various series I've started over the years (some this year) including Assassin's Creed, Life is Strange, Samorost, Sniper, The Stalin Subway (might change this as it would be to start a new series), Yakuza, Nekopara, Uncharted, Far Cry and Leisure Suit Larry I also have a few games outside series, an expansionas well as a start-up of a "new" series with Elder Scrolls: Arena on my list - but 25-68 hours does sound like a lot in that game.
I haven't made my secondary list yet but might skip that next year or it will be another completion list or a plan I've had for a long time: Physical gameplay! I already do play a lot of physical games on my platforms, but on Windows where I do play mostly I usually stick to Steam games to complete that too big library I have there - my floor to ceiling window in my office which is modded into a shelf is filled with PC and Mac keep cases with games that needs to be played, and I have a chest drawer filled with games for consoles - and boxes with tapes and diskettes for vintage systems!
Next years primary list contains the following platforms: DOS, Windows, Linux, Macintosh and PlayStation 4 - but my total list of platforms at home and storage is 38 including those five: some of them I won't be playing on (Odyssey 2001/Odyssey, Intellivision, GameCube and iPad) as the units I have for those need some tlc. So far this year I've managed eight different platforms.
My gaming goes where my heart takes me - not about what is newest, coolest and uppest in time 😀
So many computers, so little time...
