I would listen to the community, try and make this game better. Stop with all the bullshit money grabbing updates, and maybe release a "premium membership" if we're struggling for money.
I would change the pvp system, and also add many many new high leveled bosses. I would advertise the game much more, like WoW is doing. I would basically try to make the game last another 10 years.
- Fix the game engine so the lag is gone or minimal.
- Bring back RS 2006 on other servers but keep the current RS as some may still like it.
- Listen to the players more.
I would have a maxed account with anything I wanted (obviously). But I would keep RuneScape the way it is. If you started adding too much it would become very big and require alot of requirements to run.
I would try and make it more interactive & more interesting for the community, I would try and make it more interesting for higher levels by adding new dungeons, minigames, skills, quests and a whole lot more.
As laptop said I would like too see different servers of past runescape, like some with the BH craters and some with pvp world. Also I would add more bosses with a lvl cap to get to, such as a 3-67 68-100 and 101-138, each with their own specific drop table so all players are able to make money no matter their lvl
I would make it a good game again, and I would put a version of RS 2006 on the website for subscribers and veteran f2p accounts. I would also get rid of all the crap updates that they put in, such as SoF, Auras...
I would for sure change SoF and that BS, then remove the horrible lag I get at times (Because I know they have the resources to do that), listen and see what the fans are really wanting and try to work with my team towards the goal of the most enjoyable game. Last of all I would make something I would want to play, I believe that is how the game started out but money went to Andrew and Paul's head.
