The game is challenging but if you are willing to learn from your mistakes and adapt you will be fine even playing solo. You should check out this thread: NEWBIE RESOURCES & ONLINE GUIDES AND WALKTHROUGHS (All the help you need!)
Also if you are looking for co-op, you should mention your Soul Level and region so people can see if they can help you
I was actually doing some co-op this past weekend with someone from here. It is still semi active but you will rarely get invaded and most likely will not have to fight another player for the 3-3 boss.
We played for 4 - 6 hours over a couple days and only invaded twice. I actually got summoned for the 3-3 boss fight.
Yeah, I see alot of people in game(North American version) so there are plenty still playing. I'm not sure what the peak times are but I still get summoned most anytime except real late. Hardly get invaded lately but that might just be due to level or bad timing.
I started a new character two weekend back. I forgot how annoying the bridge with the dragon can be.
I might just be convinced to do some co-op is anyone is interested. I'm out of town this weekend, so maybe the following one?
I think that after Dark Souls came out, most Demon's Souls fans migrated. Dark Souls is very much alive, but when I played Demon's Souls it was a little difficult finding anybody to summon. I believe that if they made Demon's Souls available for download off the Playstation Store, that would really revive the game.
Lol Sushi *giggle*
That dragon scared me so much xD
I can still find a lot of activity on Demon's, even some new faces that have come over after finishing and loving Dark Souls
