1. You have enough content and achievements to do that. You can choose your own way of playing depending on how much time you want to devote to it, unlike MMOs, which are paid (subscription) and often hide a time-consuming acquisition system in order to get you to pay a subscription for a long period of time. Guild Wars is much more accessible and free than a paid MMO. Leveling is simple, there are no supreme, very expensive weapons that are more powerful than others, etc.
2. You can't fly, jump, or swim. Guild Wars 2 has this advantage, which Guild Wars 1 unfortunately does not. Nevertheless, the world remains beautiful and attractive. You have an exploration title, but it boils down to walking and discovering the map, not an exploit to discover a specific location, as in Guild Wars 2.
3. Play in the US zone. To find players, the capital of Nighfall, Kamadan, is the main place to trade. There is also the Great Temple of Balthazar (for PvP) and Embark Beach, which can be an interesting gateway. These last two also have NPCs for Zaishen quests (daily reward quests).
4. I'll redirect you to the official wiki -> Hall of Monuments The wiki is a database that I strongly recommend you keep handy if you have questions outside of Legacy and Reddit. The wiki is very comprehensive. If you are looking for builds (meta), there is another site here -> https://gwpvx.fandom.com/wiki/PvX_wiki
Don't forget to find a guild and, if necessary, stay with it or find another one (If you have played Guild Wars 2, perhaps a guild that plays both games.). The goal is for you to feel comfortable with the people in it. It's with your guild/alliance, that you can plan and organize your outings in the game. Without them, it's very random.
