For the MMORPGs that I’ve played more seriously, I have invariably at some point created a record of my various characters progress. Since I’m a computer scientist I tend to use spreadsheets for simple lists of such info. On my computer I have such spreadsheets for LOTRO and Everquest 2 to track character levels, crafting skill or level and other notes.
I initially created a similar file for FFXIV to track class and job levels (admittedly available in-game) but also other related info like the location of class/job trainers. I have a long since abandoned sheet for my WoW characters still on the computer as well – who needs a spreadsheet when you have the Altoholic add-on to do all the work for you?
But I have used spreadsheets for other purposes in other MMOs. In Neverwinter I created a spreadsheet to act as a checklist of the companions that I’d collected on each character. I also had such a file to track companion gear across my alts in SWTOR for a while, another sheet that’s no longer needed in the modern game.
Do you keep spreadsheets or other out-of-game files to track things for your MMO gaming?
