I have to say... my fondest memories of RO come from the mod days. I preferred the style of the maps... Jucha, Rostov, hell, all of them for the most part. I get a little weary of all the tank maps in Ostfront. Running for 5 minutes to get somewhere, then dying... and repeat gets old. This isn't a knock though, I just stick to non-tank maps and have a great time with those.
On the flipside though, the gameplay has definitely been polished. For the price, it's unbeatable. I bought it when it first came out in stores for full price... something like 30-40 bucks and feel like I've gotten more than my money's worth... I almost feel guilty.
