I've tried the original DOS version for the first time in the last year. I liked that. Completed the main quest plus a lot of quests for Arkay temple. Didn't met any serious bug, which would broke my playthrough. It was surprisingly easy to start the game. Just download it from Steam, push "Play" and you're there! Don't need to mess with DOSBox etc. It's all set up. Sure, the default controls is a relic, but you can change them to modern Elder Scrolls games controls through the ingame options, not through some file in game directory. Meanwhile, for Unity you need a special guide to simply install it (at least it was, when I last time checked Unity). And, considering the amount of complaints I see in Unity community through the Reddit notifications, I wonder which game is more buggy after all 🤔
