Level 27, have three different kinds of suits - Raider (upgraded to Raider II), T45 with some mods and an almost complete X-01. Actually I have around 7 suits in total. Even Dogmeat has different armors (no powered dog barding yet though). I do need to go around to all my power armor stations and remove the cores from the suits - my first suit was in the water by Sanctuary after Preston decided to use it to fend off raiders - for days I just though the suit was gone.
The game is a ton of fun but there are things I dislike intensely: the gui layout, nothing like being in a heated fight, switching to Aid to get some meds/food and then clicking on Maps. I dislike the "esc" to get out of lock-picking...I guess the problem for me is that I was still playing FO3 right up until release (and will still play it) so my Fallout Key memory is tied to the old game. I just wish I could re-key the whole damn thing.
Having some stutters - 98% the game runs great, when I go to certain areas - slows down and gets choppy.
Couple of bug fixes for PC: when you are tying to put the cheapest water pump in a community and you have the crafting materials and it still doesn't work (can only be placed on the dirt and the pump doesn't appear) - it's because it would use your last unit of Steel. Very bizarre bug, added some extra steel components when building and now it works.
The other one is at the Castle - if there's an attack which draws away the radio guy, there is a good chance that he will just stand around asking you for power to run the transmitter but the glitch is that he won't sit back down (after building 5 generators and then researching it and then reloading it to before I built the generators). Basically the Minuteman radio station goes off the air - no fix for it.
