I really don't think everyone is not an addict because of lack of opportunity. If anything I would say many addicts arise from an attempt to escape a reality that does not meet their needs.
True but I often felt the push pull of the two groups. Especially in mmo's. PVPers tended to be the challenge minded while PVEers tended more toward the role players. I often would chat about how I was just there to play with dolls.
Not really helpful in terms of gifts as they are free to play mmo's and they use keyboard and mice but both have some script capabilities which allow for one to be able to play alternating between keyboard and mouse or not use mouse at all. Its the cryptic games champions online and star trek online. One thing you could do is play them yourself and learn the scripting and then gifting them useful scripts. with champions online turning the block to a toggle is the big script thing and with star trek online its making an emergency power to spacebar one (this is reference to a script where tapping space works through all the abilites put into a shorcut area that can be swapped out). really basic ones will dump everything into spacebar but more nuanced ones will have a key for low cooldown abilities and one for long cooldown offense and long cooldown defense. there really is no limit to the messing around.
