A good deal of articles (mainly skilling but also battle ) in the two games you can just click on a resource/monster and only wait till until your bag is complete or source depletes. You get logged out after 5 mins of inactivity though. RS3 allows faster progress using more input for most activities. When you first begin you'll most likely need to be engaged to understand it and move through the early levels OSRS Gold For Sale. Saying this there is lots of articles which requires a lot of attention (bossing/dungeoneering/minigames etc). As a brand new player you probably won't receive the full advantage of being a member, I would say wait till you feel you're missing out by being f2p or need to learn more about the map longer. There's probably a couple of hundred hours of gameplay at the free edition.
There's no accurate better in my opinion. It is just down to a question of personal preference. That said a lot of that which OSRS is graphically, interface and gameplay wise may be approximated with settings in RS3 (like smallest graphic settings and using legacy style interface and combat). Yes. Especially while playing a different game, watching a movie, or anything like this. There are a whole lot of activities related to leveling in RS which do not need much of your active attention. It's also low resource. So on an adequate machine it can readily be conducted along with other graphic things.
I would advise having all battle stats to 60, having a entire level around 1200 and having done all completely free play quests prior to starting in on a membership. While you can benefit from having members to the very first day. You will be a good deal less gated and able to get directly into the lower tier of all of the members content how I prescribe. Because there are a lot of areas which are gated by quests. Those quests often have free play quest prerequisites and that I believe the majority of the members equipment (worth having) starts at about grade 60.
I've played with a lot and it's a great game to play actively and also"semi-afk" second screen distance just like you mentioned. There a large number of skills that are dull and only straight afk time sinks you can just chill watching Netflix play league while you get profits on the second monitor. But there's also plenty of activities that could require more principal monitor and busy playing like combat, bossing, quests etc.. I'd say osrs has more of a grindy texture to it also includes a smoother pair of gameplay using its own tick system mainly because of graphics quality imho.
However there is a lot of game mechanics which may be discovered to be"optimum" or efficient etc.. RS3 is somewhat less grind heavy or at least the xp rates are inflated therefore getting to greater levels is much easier and faster and there's a completely different combat system that is close to a WoW/ classic mmorpg style just done in a tick system of.6 minutes a tick. Personally I've spent a considerable more time playing RS3 over my osrs accounts as a result of graphics and eventually having a computer that will run everything on ultra and keep 70+ frames readily.
I have more or less"finished" both versions of the game, but I began rs3 way back when it was the old version of runescape 15 years ago so my perception of this new RS 2007 Gold player experience might not be the best, but from attempting it on new reports and alts I could fairly accurate give my view here.
