Wiki-Edits. The End of me.

So, I just started really going on Wiki edits here on the site. I got a bag of old instruction booklets and stuff from my parents' house and I wanted to do my part to fill out some of the more obscure stuff on the site. I love finding some really nice pages. Seeing that people loved an old game is really awesome, but damn. Filling out some of these sets of credits is going to be the death of me. It feels like it takes forever, but it is nice that somebody put most of the person pages in. 
 
How do you do it? Those of you who love the wiki editing, do you sit down with a game and an instruction booklet (moreso on older games) and fill out what you can?  
 
Maybe doing credits is a bit unnecessary, but I like the idea of filling out credit history if only to retroactively fill out person history on the site.
