So I've recently been gifted some MS points, and I was thinking of buying the snowblind mappack for gears 2 and probably the legendary mappack for halo 3 as well.

Being that I've never done this before I was wondering if someone could tell me if it's worth it to buy map packs, or would I be better of buying something else with the MS points

I would buy a game unless you play online Halo 3 or Gears 2 a lot.

Get Castle Crashers.

I just used points to buy Operation Anchorage for Fallout 3.  Seems worth it so far.  Its for the PC version, but the points work the same for the Xbox 360 version.  Of course you'd need to have and like Fallout 3 for that to be a better choice on what to spend your points on.  I also heard the add-on for Mass Effect is worthwhile.  Was thinking of getting that soon.

buy the map packs

If you play Halo 3 online you absolutely MUST get the map packs!

@euphoria tried the castle crashers demo didn't like it

@Ausfalcon , yes the mass effect dlc has been recommended to me by a friend to bad I hate the original game

yes i love the map packs / or get banjo-kazooie or banjo-tooie

The Snowblind maps are actually pretty good Horde and Multiplayer maps.

Courtyard and Underhill are great horde maps, the remake of Fuel Depot is nice and all of them are pretty fun execution maps.

@TRios
yeah I don't see much value in the combustile mappack though
