Budgeting for Impulse Spending

I'm a gamer girl and a geek - two titles I've never denied.  With this in mind, I beg that you indulge me in the ridiculous debate with my inner spending demons that is to follow:

Not unlike summer blockbuster movies, it seems to be that time of year when hot XBox 360 titles are being released.  Having saved so much money in preparation for my new house, I am viewing the next couple of months with uneasy trepidation.  Will the grip on my savings account loosen for the sake of what may end up being momentary entertainment?  Or perhaps, with a budget, it's possible to indulge on a game or two without putting my household payments in jeopardy?  This may require more foresight than I care to spend on the matter, but it's something to think about - I know that I am a notorious impulse spender, and seeing those games popping up on store shelves is not going to help.  Do I simply avoid game retailers all together, or do I allow myself a "gamer fix"...so long as I keep the price tag to a minimum?  Knowing me, I think the smart thing to do is just to review the upcoming game titles and decide which ones I "have to have" over the ones I'd "like to have".  For example, Bioshock 2 and Mass Effect 2 are a must - especially considering that I've played the first games in both series and I'm 100% in love with them; Prototype and Batman: Arkham Asylum are slightly lower on my interest scale, if only for the fact that I have no previous experiences with these titles to decide if I'll like the game structure.  So if I concede to the purchase of two games (at $59.99 each) while holding out on two others, that seems like a fair bargain considering my previous inability to deny myself the pleasure of instant gratification.

What with me being so financially prudent lately, I don't think it's that big of a sin to gift myself a present or two.  ...however, we'll see how I feel about my dip in funds once I get my hands on my new house!
