I've got over 30 hours on Baldur's Gate now. I'm getting more familiar and accustomed to the D&D 2nd edition rules. I had some more experienced players explain a few things like dual- and multi-classing, read up on a few game systems such as party alignment and reputation, and have learned a few other things just by experience, such as the situational utility of spells that do things like boost resistance to petrification and abilities like Find Traps or Turn Undead. Learn by doing works, to some degree.
I've more or less settled on a party setup I like, with three melee fighters, my PC who is a Wizard Slayer (fighter kit), Minsc the Ranger dual-wielding maces, Dorn the Blackguard with a 2-handed sword, and three ranged characters, Imoen the Thief on Bow, Dynaheir the Invoker with offensive magic, and Viconia the Cleric handling crowd control, buffs and debuffs, healing, and slinging bullets. As long as I keep my party's reputation in the mid-range, 9 to 12, everyone seems happy enough.
I haven't made a huge amount of progress through the story just yet. I'm hunting down a base of operations for the raiders that have been terrorizing trade routes from Amn (which I gather is to the south) to the city of Baldur's Gate at the north end of the Sword Coast. It's somewhere in the Cloakwood, but I don't have the foggiest idea where the Cloakwood is. It's not marked on my map, which is odd. I really feel like one of my 6-person party should know where it is. Oh well, the hunt for it has taken me on a few interesting adventures already, and every bit of experience helps. My party members are all 5th level now. I don't just go online and look up the location of the Cloakwood because I'm sure I'll find it eventually, and the roleplaying is interesting. I keep expecting it to appear on my map once I get near. We'll see.
Destiny. Well, I've been playing it most days since release, but never for more than about 45 minutes. I'm still on the Moon missions, only level 11 with my Warlock. It's good, and fun, but I get worn out on it pretty quickly each session. I don't think the campaign is all that interesting so far. The locations have none of the spectacle of Halo's levels, and there are no characters to speak of. I think this game was trying to go immediately from first to fifth gear, starting off in a mode that makes it lend itself to play like you would with Diablo III on your fourth character solely in adventure mode. I think that's fine in some respects, but it can also just put you that much closer to feeling like you've exhausted the worthwhile content if you are not completely head-over-heels in love with the game.
