Great question posed by Stabs in a comment after my blog post in which I admitted to having bought 42 games last year and only played 13 of them thoroughly.
"Do you see it as a problem that you never or briefly played so many games - are you too impulsively buying games you're not really going to play or is it still worth getting them to have a brief look?"
I gave a brief answer in my own comment but I will try to expand on it here.
I do try out the majority of the games I purchase and I do manage to immerse myself more completely in a small number of them. In fact once I latch on to a particular game I often immerse myself quite completely in one game for a few days, or even a few weeks. One of my greatest gaming pleasures actually comes from completing games and once a game gets its hooks into me I will stick with it quite doggedly to the end of the main campaign. For this reason I quite like the modern trend towards shorter more intense single player games and I simply ignore gamer achievements, DLC and other mechanisms that are used to artificially add longevity to games.
Of course with so many games to play it does sometimes happen that I get distracted from a game before I reach its natural conclusion. If I wasn't enjoying the game that is not a problem but there are a small number of titles I regret not having played more thoroughly. I tell myself that one day I will get back to them but it rarely happens.
My play-style does limit what I can hope to achieve in certain types of game. Competitive multi-payer gaming of any sort is more or less out because I am not prepared to commit for long enough to build up any ability. MMORPGs could be a problem but I appear to have struck a comfortable compromise with Lotro where I play for a couple of months and then take a year break and Turbine have been kind enough not to add content at such a rate that I cannot catch up.
Gaming Acquisitions since last Friday: Disciples 2 Gold Pack (Original Game plus two expansions), Batman Arkham Asylum, Lotro Europe F2P preview client, Dogfight (Aerial combat).
Games played since last Friday: Disciples 2 (half way through tutorial), Batman Arkham Asylum (about two thirds of way through main campaign), Lotro original (Joined a kin raid to Barad Guldur last night), Lotro F2P preview (spent half an hour starting a new character and getting him to Archet). Dogfight (installed and played about 10 minutes of tutorial. Might join RPS event on Friday).
