The first MMORPG I played, Everquest, took up a significant part of my life - and my career, because the foreman on the HGTV house I was a finish carpenter on purchased the game and subscriptions for the crew on the job so that we could discuss job related matters while we farmed giants.
Eventually Sony failed to continue access to their servers (I don't remember details after more than 20 years), and my considerable investment of time and money in the game was all consumed by the whirlpool of obsolescence. It was kinda traumatic. I lost many contacts with people I met online, Fabled gear I farmed during Sony's 5th Anniversary celebrations, skills and knowledge that enabled me to tank dragons in raids (a quite elite position in EQ), and all the social and emotional capital I had invested in that game over years.
This greatly discouraged me from investing in games thereafter, both monetarily and in my time and attention, so more recent examples of similar abandonments by subsequent games hasn't impacted me. Calling the grapes sour hasn't otherwise done me good, but being immunized against that level and kind of loss is significant. Another game I played in the '90s was risk. This was not an MMORPG, but comparable to Solitaire that I played while waiting for downloads, or sites to load (back when online access was achieved with 300 baud modems, these could be significant time sinks). Last year I found that specific Risk game and managed to get it to work using Wine on Linux, and it's today the only game I play, in a little window on the corner of the screen while listening to podcasts and etc.
Fool me once, shame on you, Sony. Can't be fooled again, GW Bush.
I was more of a WoW guy, but I know what you are saying. Just imagine what would happen if EVE Online ever went down and all of those users lost all of their investment!
