1. When my horse slipped down a canyon and died and I really felt bad.
2. First wolf attack in the moonlight when I thought I could take a shortcut off the trail.
3. Fort Mercer when the reinforcements arrived.
4. Riding into a Mexican town and the random characters started speaking Spanish, with no subtitles.
5. Drifting down the river shooting at the snipers and seeing one fall into the river.

Not sure. At first, I was thinking "eh, this game's alright." Then I was like "Yeah, this is pretty good, but it's too long." And finally, I was like "Okay this is a great game, but god damn it :("

When i rode with my beloved horse on top of a canyon and waited for the sun to set.
Then i realized how much i was enchanted by the characters and the setting. This game is very eerie and absorbing!

When I was stuck on the side of a cliff in an intense thunder storm and I was actually, really frightened That's when I realised how realistic the game was.

I bought an X-Box 360 for this game because I had a feeling this game was the one I'd been waiting my whole life for, and I was right. This game exceeded my high expectations several times early on in the game.
Not necessarily in any order:

1. Walking around Armadillo and feeling like I'd traveled back in time.
2. The first cougar attack. It was so unexpected and startling.
3. First thunderstorm. Realistic and stunning.
4. Exploring New Austin on horseback during a starry night.
5. Perhaps the greatest moment of them all: Hunting wolves on a starry night at Riley's Charge early on in the game. I ran out of ammo, the wolves killed my horse, and I had to fend off packs of re-spawning wolves until a new horse came along. I loved how suddenly I went from collecting pelts to survival mode.

When I actually found myself enjoying riding a horse all over the place.

I would say pretty much the first time I walked down main street of Armadillo and was stunned at how real everything looked. I felt like I was in a time machine, or at least looking through a time-transcendent lens, or something.
Otherwise, I would say the Fort Mercer mission. The game is tons of fun up until that point, but that mission - which I had been anticipating - took it to another level.

It was quite early on when I was just riding through the beautiful landscape, doing side missions and just enjoying the game. Although riding through Mexico and hearing Far Away playing in the background was absolutely amazing, I think it made me realise all over again just how great this game is!

When I acquired the lasso an could catch criminals while still on a horse an drag them, in my opinion thats still the coolest thing I've done in a game

Umm there were numerous points
-First time i realised that there were so many animals and i could kill them all
-First Cougar attack
-Getting lost in Pike's Basin and then a thunderstorm kicking in

when u shoot someone and they react realistically

Fairly early on in the game, when you're still just puddling around doing chores/learning stuff at the McFarlanes Ranch.
I'd been out hunting and was on a ridge looking over the valley coming home when the first storm rolled in. I just sat there on my horse watching the wind and the rain build up and darken the landscape, I was just admiring the little specks of rain that get on the camera lens and thinking 'that's a nice touch', when the thunderclaps started going off and I was like,
'Whoa! This is amazing!!'
Haha. Must've sat there doing nothing but soaking up the whole experience for like 5 minutes or something before I realised I was just sitting on my couch at home with a controller in my hand not really doing anything more than playing a video game. Honestly how many other games make you really stop and take in the natural environment like that?
As you say, awesome.

Also when John died, and then I noticed that I was REALLY into it when I saw the people who killed him. Boy I wanted vengeance..BADLY.

cheers for that

Dude, there may be people who haven't finished this yet. Spoiler tags are there for a reason!

The missions, but most remarkable was when John died.

The intense glitching must be a PS3.
Yeah, pretty much. The glitch count went into the 30's for me before I lost count. For a 20 hour game, I just couldn't muster the justification for liking it and seeing past the flaws.

I DRINK IT UP!!!

The intense glitching must be a PS3 thing. Ive seen very few glitches on the 360 (same with Fallout:New Vegas).
I think for me it was the mission where you had to save the women at Ridgewood Farm. Was brutal and awesome. Also, the thunderstorms in the game did it for me. Theyre by far the most realistic thunderstorms Ive seen in a game thus far.

Immediately, since it was the first Xbox game I ever played. Bought myself one for my birthday plus a few games and decided to play this one first. My whole family was gob smacked at that moment XD

When I rolled into Pike's Basin with Marshall Johnson like we were Wyatt Earp's posse.
