Charts and data show the rise in XBLA prices since system launch

According to a report over on Kotaku, the average price of Xbox Live Arcade games has risen by a $1.74 since November of 2005.

Studying the launch prices of over 200 titles made available on the service, the average price for downloadable games has risen steadily in the past 46 months. Average price during the first month on the market in 2005 was under 600 MS Points ($7.31) and as of last week prices have gone to 700 MS Points ($9.05).

Games being released during Xbox's Summer of Arcade will raise that average a bit, according to data, with four of the five offerings costing 1200 MS Points ($14.99).

A chart showing popular titles released for 400 MS Points ($5) suggest that the days of cheapness are nearly over with 1200 becoming the new magic number.

Looks like the whole world is just getting more expensive every day.

More data and some pretty charts are over on Kotaku.
