The Elder Scrolls V: Skyrim is a first person action RPG with a huge open world. You play as a dragonborn and must fight to stop the dragons from destroying the world.
Pro Unrestrictive skill-based RPG system
Skyrim has no set character classes or equipment/spell limitations. Instead, it allows you to form your own class based on how you decide to play.
For example, sneaking increases your sneaking skill, hitting an enemy with a shortsword increases your one-handed skill, taking damage while wearing leather armor increases your light armor skill, and so forth. You can you play however you want and the resulting character will be a perfect match for your playstyle, giving Skyrim a different feel from other RPGs.
Pro Massive sandbox to explore at your own pace
The in-game map is absolutely gigantic. There are so many places to go and so much to do in the world, easily giving you hundreds of hours of content.
Exploring the wide range of environments, from the snowy mountains to the richly-detailed towns and cities is such a joy because of how lush and beautiful everything is. Wandering around often surprises you with new side quests to find off the beaten path, with new characters to meet and history to learn about in whichever area you find yourself in. You can get into all sorts of battles with powerful enemies or stumble into hidden dungeons with awesome loot at the end. Or you can sneak around towns at night stealing peoples' stuff while they're asleep to sell everything off for money. And there's just a ton of other intriguing secrets and fun diversions to discover as you adventure throughout the world.
Pro Deep lore rivaling classic fantasy literature
Skyrim inherits the stories and world-building of The Elder Scrolls series, which stretches back 20 years. It has numerous stories surrounding the various races (orcs, elves, lizardmen, demons, etc.), mythical beasts, gods, cataclysmic events, parallel worlds, and just about any fantasy trope you could think off. What's even better you can read the lore in books found in-game, allowing you to immerse yourself for countless hours.
Con Forgetful NPCs can break immersion
After completing certain story quests NPCs get new lines added to their dialogue based on your decisions. Sometimes the NPCs might become forgetful and return to their default dialogue, which can break immersion, especially if they talk about an event that's been long resolved.
Con Combat is too simple
Most of the time you can just whack an enemy until it dies and it involves very little strategy or planning to succeed.
For example, targeting specific body parts doesn't deal extra damage, nor can you cripple an enemy. There are no vulnerabilities, so you can't set furry forest animals ablaze easier than humans. The enemies also lack any real variation in how they attempt to fight you – they just run at you swinging wildly or attack you from afar.
Because of this the combat is very one-dimensional and can start feeling like a chore after a while. Luckily most of the combat issues can be fixed with mods, allowing you to enjoy a more varied and deeper combat experience.
Con Buggy and crash prone
While this game is not as buggy as it was upon release, there are still many people that encounter various bugs and crashes. These can happen in both modded and unmodded games and it's a common occurrence in Bethesda released titles. Fortunately, there are some community mods that try to fix most memory issues, stability issues, and general bugs.
