I played them both. And i regretted having played... the ENHANCED edition ones! Well, i have to announce in the beginning of the post, that concerning all games in general, i am a retro maniac, still living in the past (that is why i am here in GoG, and that is why my pc is full of emulators and arcades). But i couldn't help noticing many things that really, REALLY, turned me off! Despite that, i will present both positive and negative aspects, i noticed in both editions. I start, please bear with me:
Baldur's Gate 1 original VS Enhanced.
Original's pros:
1) Legendary atmosphere, started the series, great concept, good implementation.
2) A lot of secrets, glitches and loopholes, like the import-export, xp and money ones. Or the vast armies of summoned creatures. Many of you will put this to the negative aspects, though...
Original's cons:
1) Awful quest log, chaotic at best.
2) Lots of bugs.
3) No way of having hitpoints roll maximum through options, like Icewind Dale. Some of you might put this in pros, though.
Enhanced pros:
1) Graphics got revamped.
2) Many errors were corrected.
3) New heroes
4) Restored locked content from the original
5) Better way to track quests.
6) Romancing.
Enhanced cons:
1) Cutscenes are worse, without motion, only pictures changing in succession and with almost cartoonish appearance. Also, rest cutscene got removed.
2) Despite that many errors were corrected, a TON of new ones appeared, and all new patches are double-edged, correcting some issues and creating other ones.
3) They removed all the glitches, even the useful ones! DAMN! Some of you might put this in pros, though.
4) Worse experience than the original, at least for me. Especially since now 1 has 2's mechanics. The old system, choosing a kit in 2 was better. Especially since by doing this, the downsides of certain classes like the avenger got eliminated (-2 str and con at character creation, and not on kit choosing). Or the proficiencies, which were far better in poor old one (one category containing MANY weapons).
5) Feels bad, is in STEAM... Well, at least EA did not create it, it is not absolute trash.
BG2 Original VS Enhanced.
Original's pros:
1) Great artwork and interfaces, Especially the symbols with the button panels.
2) Cheese everywhere! Exploits everywhere! Examples: 5 planetars summon, simulacrum arcane spellcaster and undo the 5 creatures limit, wild mage eliminating wild surge by chain contigencying 3x Greater Chaos Shield, and many, many more! Some of you might put this in cons, though...
3) All the tricks, like familiar trick, tears of bhaal trick, etc. For some, again, this might be a con.
4) Avengers can wear some of the dragonscale armors. Beastmasters can wear black and white dragon scales. Ankheg Plate can be worn by classes and kits forbidden using metal apparatus.
5) Broken spells.
Original's cons:
1) Gamestopping bugs, like Solaufein not initiating dialogue.
2) Kangaxx. Seriously, this thing was a sick fight, the likes of which are very few and numbered across the many RPGs i have ever played.
3) If you are a good cleric, change alignment by using and evil tear of bhaal and gain a level, you do not gain unholy blight and unholy word; a real shame, since neutral clerics get both holy and unholy exclusives, damn.
4) Some Jaheira issues and bugs.
5) No pure thief to recruit, no good mage to recruit (edwin does not do divination, jan does not do necromancy, imoen does not do a worthy party member and nalia is even worse, aerie does not have 18 to either wisdom or intelligence). This might be a pro, though, actually, since making something like a Kensai/Thief for main, or a dual mage, is vastly overpowered and frequented since those good old days.
Enhanced pros:
1) Better graphics.
2) A great recruitable thief character.
3) More romance options.
4) Animations seem somewhat more normal, natural, realistic, compared to the old one.
Enhanced cons:
1) NO MORE KEEPING ITEMS FROM 1! Some of you might put this into pros, but here, believe me, you have no right, you are the devil incarnate! Congratulations! Now where on earth will you find in 2 items like the Cape of Balduran, which were 1 exclusives??
2) All cheese was corrected and thrown away from the game by force.
3) All glitches/exploits got corrected and thrown away from the game by force.
4) Now the 5 creature summon limit cannot be bypassed.
5) No more 5x planetars summon.
6) A TON of new errors.
7) Feels bad, is in STEAM... At least EA did not create it, so it is not total junk...
Generally, i wouldn't pay to buy the Enhanced Editions at all (and didn't, thankfully). Not only they are in STEAM, and we thusly support our mortal enemies, the DRM and always online lobby (let alone you own nothing materialistically you only are allowed to download your data and everything), but we also pay an outrageous sum, for what we could do ourselves by installing some certain mods, as some people already suggested. I believe with good reason that GoG versions are vastly superior, especially if you combine them with the Trilogy Mod. If you also are one of us, enjoying your game as it was way back then with all the glitches, exploits and most importantly, plenty of cheese mixed in and happily blended, then the EEs are certainly a mortal enemy of yours. Their only real positives, in my books, are displaying your roll total number, and communicating online multiplatform; for me, all of the corrections the ADD fans adored, are actually missed content and opportunism, especially the correction of keeping items from 1 or the cheese in spellcasting.
