Ratings film Nielsen has released its post-E3 purchase intent charts, revealing that Bungie and Microsoft's Halo: ODST, which drew a slightly muted response from journalists, leads "probable purchase intent" with gamers it has surveyed.

In an earlier report, Nielsen said that online "buzz" out of E3 placed four-player, 2D side-scroller New Super Mario Bros. Wii at the top of the charts of the press.

But -- so far -- Nintendo's big fall release hasn't made an impact on the purchase intent charts over an unspecified number of Nielsen respondents surveyed last week, between June 7 and June 14, a few days after the big show.

Twelve games captured 30% or greater purchase intent, which Nielsen defines as "definitely or probably interested in buying the title", as follows:

1. Halo ODST - 53%
2. God of War III - 49%
3. Wii Sports Resort - 45%
4. Guitar Hero 5 - 42%
5. Final Fantasy XIII - 37%
6. Madden 2010 - 35%
7. Guitar Hero: Van Halen - 34%
=8. Assassins Creed 2 - 32%
=8. Need for Speed: Shift - 32%
=8. Need for Speed: Nitro - 32%
=8. NCAA Football 10 - 32%
12. Beatles Rock Band - 30%

Interestingly, E3 seems to have had little effect on the purchase intent chart, according to brief comments published alongside the Nielsen report, with movement of only 1-2% at the largest reported for "most" of the titles.
