Play with a no reload ever in BG1 makes this game very very hard.. So much random instant death in the game.. even if you know what is coming.. Death spells, stone, crit hits ect.. there are tons of ways to die instantly even if you do everything right...
To be fair, a lot of that is inherent in AD&D 2E. That said, Bioware could have just as easily started the PCs out at level 3 to give them a fighting chance, which they managed to do elsewhere *cough*Torment*cough*. Furthermore, BG adds in difficulty that wasn't present in the original P&P game, namely that failure to memorize a spell didn't result in the scroll being consumed, but only required you to wait until you got your next level to try and learn it again; here, you fail your roll, and you can kiss that rare scroll goodbye. This gets especially bad in BG2 where there are certain vital spells that only have one scroll (iirc), including breach, which is one of the very few things that reliably allows you to hurt enemy magic users.
Yea, that is true... BUT,, i will say, being this a computer RPG, you most likely have your int at 18 if you are playing a wizard..
If you were truly playing dungeons and dragons, the way to create a character is you first Roll your dice one time for your ablities, and then you choose your class.. the old school way was to roll 3d6, and place in order. than you got to pick your class. Later people adopted it, with 4d6, or groups of 4d6x7, drop the lowest, and place where you want. but even then you did that before picking class... But i digress.
You can buy those +int potions, i think there are +3? Plus spells to increase your chance of learning i think. Doesn't luck come into play? Perhaps not.. But still there are other INT boosters, and potions with +5 int. (at least one i know of, which i always save) Then when it comes time to learn all those spells i have been saving, I Buff up INT as much as possible and then you rarely fail on learning. In BG II, you have much more money, so buying those potions is not such of a big investment. But sure, sell some loot, buy a potion for when you are going to learn spells.
All that said, not doing things like reloading, and going with your character rolls, can really increase your fun/challenge of the game for later replays. It is just not something i would recomend from the get go your first time playing.. It just is not fun to learn that way.
But later it is something you can self imposse that really does make this game shine on the 3rd, 5th, 10th play's.. I personally never made it through on a no reload game.. Eventually my main character would get disintegrated somewhere down the line.. I did make it to the city of baldur's gate a few times trying.. :) Most of it was me being to daring with my main character, after all they are the hero.. Kinda cheesy if you just protect them the whole time and not take risks right?
But another fun self imposed rule, is to never rez any fallen character,.. if the character dies, pick up the loot, and find someone to replace.. If you are playing a bit fast and loose, you can go through a good portion of the NPC's before all is said and done.. :)
the other side of scroll use, is sometimes instead of saving those key spells and you use them for a battle because that was the final resort.. Having a playthrough, with out some key spells, really makes you play the game a lot different. Never using fireball for example, Or a no summon game, outside of single use scrolls.. You know, something that makes the next play something vastly different than power gaming the game.. Some of my most fun games, where games i never finished, but had a hoot playing till i gave up on um.
