How many hours have you spent playing Touhou?

PCB: 126
IN: 87
MoF: 105
SA: 345
UFO: 10
TD: 126
DDC: 11

Total: 810

None of these are completely accurate but they're pretty close. This doesn't include any time spent on practice patches, which could easily mean I've played SA for about 50 hours more. I've played the other games so little that I didn't feel the need to include them.

My playtime (all of them are estimated, I included everything):



Total:~729 Hours
Without Fangames: ~527 Hours
Without Fighters+Fangames: ~349 Hours
Main games only: ~245 Hours
Fighters only: ~178 Hours
Spinoffs only: ~282 Hours
Fangames only: ~202 Hours
(tfw didn't play Main games that much)
It's probably accurate

mof 40-60h
pcb, eosd, gfw , pofv, ufo, ddc, td, sa 5-20h each
IN old file 100~, first new score.dat 835~, second score.dat 30~, current score.dat 110. nonspell practice 30-50
lolk 0

I'd estimate around 4000 or a little less, about half the playtime is on StB+GFW. I also played EoSD, DS and PoFV a lot and have over 100 hours on PoDD, UFO, and I think IN. Everything else is sub-100 hours. I actually played the maingames quite a lot when I was newer.

Edit: more details.

StB: 1200~
GFW: 850~
DS: 300~
EoSD: 300?
PoFV: 250?
PoDD: 200?
UFO: 150~
IN: 100~
PCB: 80~
SA: 60~
MoF: 45~
ISC: 40~
TD: 30~
DDC+Demo: 25~
LoLK+Demo: 20~
MS: 20?
LLS: 15?
HRtP: 5?
SoEW: 5?

EoSD, PoFV, PoDD are very difficult to make estimates for... i might be undershooting them, but im definitely not overshooting them. I could see EoSD having 400 hours considering how much I used to play it, but I'm leaning more towards 300. In StB I can make a good estimate thanks to the photo counts.

Putting all these together ends up at 3695 hours. So I'd say, more than 3600 hours, but less than 4000, is relatively safe estimate.

As a bonus I made estimate for how much I played each year...
2010: 50 hours. I found Touhou here and played almost only 6-8, especially 6 and 8 extra stages.
2011: 400 hours. I spread my time out across the games
2012: 600 hours. I played a lot of StB, UFO, EoSD, and discovered how much I liked GFW and Phantasmagorias so I played those too
2013: 400 hours. slacker year with some eosd and gfw scoring
2014: 1400 hours. Most of my StB time is from 2014 and spent months playing almost the whole day sometimes 50+ hours a week...
2015: 900 hours. Lot of GFW, also DS/StB.

so my playtime increased when I began specializing in games... Especially because StB was so addictive and I could not stop grinding it...

EoSD: 30
PCB: 28
IN: 29
PoFV: 1
StB: 10
MoF: 17
SA: 27
UFO:28
GFW: 3
TD: 12
DDC: 8
LoLK: 3

Total: 196 hours
I'm probably underselling myself here though, so I'd ballpark 220

Guessing because I don't have the old data files anymore.

EoSD: 80 hours~
PCB: 70 hours~
IN: 300 hours~
MoF: 70 hours~
SA: 40 hours~
UFO: 40 hours~
TD: 15 hours~
DDC: 2 hours~
LoLK: 9 hours~
Total: 626 hours~

I probably played more or less but it is somewhere close to that number, probably.

Ehh, more than most of you, less than friend.

PoDD ~150
EoSD ~100
PCB ~160
IN ~650
PoFV ~200
StB ~70
MoF ~100
SA ~150
UFO ~50
DS ~100
GFW ~60
TD ~55
DDC ~10
ISC ~3
LoLK ~Top fucking kek, 0

So together it's like a little over 1750 hours total. Do note that most of them are more than what is noted here, but due to going through different score files several times, I just made a conservative assumption on every game. I particularly don't remember how much I played any game like 4-6 years ago. These play times are pretty much 2012 onwards. Overall, it could be as high as close to 2100, potentially.

I don't know. Games like MoF, SA and UFO has had me playing for about 150-200 hours each. Rest of the games in the series not so much.
For most of these I lack the numbers to give a proper estimation but I guess to answer your question, not a lot. Need more. A bit of actual effort could help. Hah, as if that'll ever happen
