I do try to rein in my acquisitive tendencies when buying new games but holiday sales and gaming bundles have thwarted my efforts. I do have a personal rule not to buy a game unless there is a real chance I will play it in the near future. Holiday sales present many games I would like to play all at the same time which inevitably builds up backlog. Bundles on the other hand may have one or two titles which I genuinely want but come with a half dozen unknowns that may or may not be interesting. There have been bundles where every title turned out to be a stellar gaming experience and there have been bundles where nothing has live up to its hype. Regardless they all add to the clutter in my Steam library.
The grid view is my current last hope of in desperation because sometimes my eyes will pick out the picture of a game even if I cannot recall the title but I wish there were better search tools available for the library. Being able to sort by store classification (Shooter / Action etc) would be a big help. Not only would that help down narrow the search for a particular game it would also be a great help for those times when I feel like playing a shooter / an rpg / an rts or some other genre and would like to see what games of that type I have. Being able to sort by date acquired would also be useful. That way I could finally find all those games I bought during the Christmas sale.
