Not sure if you wanted this to be limited to Aion players or not, but figure I'll jump in.
I belong to a non-denominational church, which (I think) technically means it's classified as a Church of Christ (the church name just contains "Christian Church").
I'll be honest, there's nothing I don't like about my church. Our pastors teach right from the Bible, and while there are some places the four of them may not agree completely (as one was trained in a Calvinist seminary, the other in a Wesleyan), they respect each others opinions and make sure they teach both possibilities very clearly and offer scriptural support for each position.
Why do I meet with them? I love my church family. Sure, we have our quirks and differences, but it's a big building full of people that love God and others. I love the fact that people genuinely care about each other.
For example, when my dad when into the hospital, he only told three people... and more than 25 showed up over the next week to visit him, many more called my stepmother, sent cards, and even delivered food. Several people went to do "little" things like mow his yard while he was bedridden.
