Total Silver: 4

Gold Trophies by Worth

One Gun (40G)
Maxed Out (75G)
Epic Tier 3 Engineer (150G)

ANALYSIS

Bronze/Silver split lies at 30G, Silver/Gold split could lie at 50G, if not for the single 40G outlier. This could just be a result of , "Oh shit, we've allocated all the rest of the gamerscore, not enough left to make One Gun 50G", but that's purely speculation.

CONCLUSION

Ignoring the one outlier, we can reject the null hypothesis and fail to reject the main hypothesis. Still more testing required. Three games so far, and I'd say I need a minimum of 5.

More testing required.

Exchange Rate Notes #1: Fallout 3

Been a while since I've posted, yes. In the intervening time, I've acquired a PS3 to sit alongside my 360. As you might already know, they too have achievables, only they call them "Trophies". And unlike XBLA, they merely rate the tasks as bronze/silver/gold (also platinum, but this is exclusively for 100% completions). Seems a bit more limiting in scope, if you ask me.

On the other hand, it has given me a scientific hypothesis to formulate and test.

SCOPE: Cross-platform games, that 1) are available for both XBox360 and PlayStation3, 2) have identical achievables (X360 achievements, PS3 trophies).

HYPOTHESIS: For any game within scope, an achievable with a given trophy level on PS3 will fall within a specific Gamerscore range on X360.

NULL HYPOTHESIS: There is no correlation between Gamerscore value and Trophy level.

PROCEDURE: Full list of Achievements will be acquired from TrueAchievements.com, and full list of Trophies will be acquired from PS3Trophies.com; lists will be compared. Minimum and maximum Gamerscore amounts will be determined for each Trophy level. Platinum Trophies will be ignored, as they are given exclusively for 100% completion, and Achievements for same on XBox360 Games are not always included.

Now that this is established, apply the procedure to some games. I'll start with the game I'm currently working through, Fallout 3.

Who Dares Wins (30G)
Free Labor (40G)
Operation: Anchorage (40G)
This Galaxy Ain't Big Enough... (40G)

Total Gold: 7

ANALYSIS
If you just look at bronze/silver, there's a clear dividing line at 20G. Only one achievable crosses this line (Yes I Play With Dolls, 10G/silver). If that were all, it could be dismissed as an outlier.

Adding in the gold trophies makes this result a bit more murky. I expected all of the gold trophies to be worth 40G or more, but more than half of them were less than this.

It might make more sense if Bog Walker(40/S) and A Meeting of the Minds (20/G) had their Gamerscore values switched. It would fit with the common pattern, established with other DLC packs, of the last quest being worth 40 and the extra non-quest task being worth 20.

CONCLUSION: Insufficient Data
Based on the data I've collected from this game alone, the hypothesis has been disproved, and the null hypothesis has not. Can't come to a final conclusion just yet, as I've only collected data for one game. I figure I'd need to do this for several more games.

More posts in this series coming.

Achievables #2: Ms. Pac-Man

Yes, there already exist achievements for the XBLA release of Ms. Pac-Man. In my opinion, they're not particularly creative.

Out of 200, 90 is for eating one of each fruit. A further 25 is for eating all 4 ghosts off a single power pellet, and 30 more for doing it 4 times in a stage. 65 rests on the ability to reach level 22. These achievements are only slightly different from those they gave to original Pac-Man. Furthermore, they violate a key rule which I've just made up:

At least one achievement name must attempt to be funny or clever.

So if I could do this whole thing over, here's what I've got:

Wakka
1 - Eat one dot.

Wakka Wakka
10 - Eat 1000 dots.

Wakka Wakka Wakka
25 - Eat 25,000 dots.

Wakka Wakka Wakka Wakka
50 - Eat half a million dots.

Power Up!
4 - Eat a power pellet.

Wakka Wakka Fruit

40 - Eat one of each type of fruit.

Wait, That's Not A Fruit
20 - Eat a pretzel.

30 - Consume all 4 power pellets on a level without consuming any ghosts.

I Ain't Afraid Of No Ghost!
10 - Consume all 4 ghosts in a single power pellet.

Total: 200
