1:G,2:D,3:F,4:E,5:A,6:D,7:A,8:C,9:A,10:B,11:I,12:H,13:F,14:G,15:O,16:T,17:I,18:C,19:A,20:D,21:I,22:H,23:O,24:P,25:C,26:A,27:K,28:C,29:8
1 G (chaingun is my default main weapon for at least half of nearly any game I play)
2 D (basic shotgun is a useful weapon for such a short stretch of time, end of level 1 to until the combat shotgun or chaingun is found, and useless otherwise; and even when useful it is still only marginally more useful than the pistol)
3 F
4 E (envirosuit is just not as useful as the others, although definitely a good addition to the game; I very rarely use an envirosuit outside of the Lava Pits)
5 A
6 D (magazine mod is only ever useful on the BFG, in games I play; if only you could use it on a rocket launcher...)
7 A
8 C
9 A
10 B
11 I
12 H (computer map just not as useful as the others, and frequently multiples show up on a single level)
13 F (former captains are fun to fight in both early and later stages of the game, well-balanced, a life-saver for its ammo drop when you are in Hell)
14 G (cacodemon is a frustrating enemy, I have died way too many times to them, in Hell's Arena (where they make sense, after all, you should die often in Hell's Arena) and later in the game, where they too often get the jump on me in Hell and hit me with a fireball, doing still surprisingly much damage, before I can kill them)
15 O (Necroarmor is almost always used once found, and the regenerating mechanic is fun and unique)
16 T (Phaseshift Boots are common but very rarely useful to me)
17 I
18 C (Chained Court is easy enough to be boring on difficulties less than U)
19 A
20 D
21 I
22 H (teleporters seem rarely used and rarely an important part of the game, outside of the Spiders' Lair; I wish they were a bigger part of the game)
23 O (Whizkid is probably the most fun trait, although Eagle Eye is the one that is most essential for me, in surviving)
24 P (Badass is the only trait that has never been useful to me, even in beating Angel of Masochism)
25 C
26 A
27 K (Ao100 is by far my favorite challenge)
28 C (AoDarkness is by far the boringest and most uselessly frustrating challenge, to me)
