RQs continue to form the backbone of my strategy and CR's guide is still a great guide to follow to maximize RQs in any city. Yes, per Dulahan, you can build an Arc early, rush it to 80 for FPs, medals, and 'Spend xx FPs' RQs, but if that is the only means of wealth in your city, your entire game then becomes all about the Arc.
If you're not hunting for GBs to 'Spend xx FPs' on, you're city is starving. I built a strong city based on CR's strategy, then used that to power my Arc to 80. By the time I built the Arc, leveling it was quick and easy in combination with some 1.85x threads. By then my HMA city was, with RQs and overall city FP production, producing over 100 FPs a day.
Now with an Arc 80, without doing any 'Spend xx FPs' RQs, my HMA city is close to 200 FPs a day, just from GBs, Special Buildings, SoKs, etc. My game is not dependent on my Arc, or the constant use of my Arc. My GBs level quickly just from the base production of my city. Why is this important? Let me give you a real world example from this week.
I'm in a guild that is heavy into GvG and filled with a bunch of advanced players. Our baseline GE requirement is 48/48 every week. Most weeks all 60 players finish 64/64. The moment SAM was released, 1/4 of the guild aged up into it, with Virgo Projects going up left and right, and everyone racing to the new finish line.
Everyone in the guild was leveling their GBs so members could spin RQs to get the SAM goods needed to advance. I jumped into the fray, on the hunt for medals and called a few top spots on some GBs being leveled. I did't even think about the SAM rush happening in the background. My guild leader explained the deal and asked me to lay off the top spots on the GBs to let the SAMies grab them to run the RQs they need to generate goods.
If my city was solely dependent on FP profits from using my Arc, and 'Spend xx FPs' RQs spun with my Arc, this would be a problem. My city would be starving. Instead, I'm using my abundant city FP production to prime my GBs for leveling, still adding a level a day, taking full advantage of all the SAMies eager to 'Spend xx FPs.' I'm cool grabbing the cheap seats for a week or two until things settle down again. Also, when RL gets in the way, or I don't feel like snipe hunting, I still produce more goods and FPs than I can ever use, and up my GBs go.
The place where CR's guide is most outdated is his advice to eschew Special Buildings in favor of 'Produce 24' buildings for more RQs, but SoKs were the most powerful thing. By the time Dulahan wrote his Arc 80 guide, a new crop of FP producers were on the scene, and he rightly advised to put a preference on overall FP production, replacing RQ buildings with better FP producers as they were acquired. The downside of Dulahan's guide is it also suffers from a sole focus. Getting an Arc to 80 and using that to power your city. Okay great, but that's all you got.
I often wonder if that's why they quit. CR failed to adapt to the changing realities of the game allowing for the new crop of FP producers or fully understanding the power of the Arc. Dulahan built a guide all about the Arc. When he quit, I remember him posting about, doing all he really wanted, seeing the rest of the game as more of the same, and it had become too time consuming. I can imagine why.
Players who simply dismiss CRs guide as being outdated are being shortsighted. I've seen tons of players jump into Dulahan's guide, IA - HMA. They spend all their meager FPs to chase down Arc prints, then spend all their meager FPs to buy Arc goods, then spend all their meager FPs trying to level their Arc. Then they finally quit the game when they discover their meager FPs from their underpowered city, will not be helped by the meager extra FPs from their meager Arc which now demands it all.
I like that I used a blended approach. I have a powerful city with an Arc 80. I don't have a powerful city because of an Arc 80. At it's core I have a powerful city because of CR's guide. The interaction of SMB, LoA, coin and supply boosts from special buildings and the tavern, the levels of CF. I continue to use his core philosophies to maximize my ability to complete RQs, which help maximize my per tile productivity.
As an example, I've balanced my coin boosts so that collecting either 3 SoKs, or 2 SSWs completes one 'Collect XX coins' RQ. Now, pulling down 2 Alchs (a CR no, no) to replace with either of those FP producers doesn't lose me an RQ, I just replace one 'Produce 2x 24-hour' RQ, with one 'Collect xx coins' RQ. CR's guide will continue to form the underlying structure of my city, but I'll also continue to follow Dulahan's advice and prefer FP producing buildings over 'Produce 24' buildings.
Each of the guides has it's pluses and minuses and suffers from the same problem. Each is written from one players' perspective around their particular goals. For players looking to 'follow the dots' to FoE stardom, all the guides have their faults. For players looking to 'connect the dots' and master the game by understanding the game, the key principles taught in each of the guides still stand. Those key principles will continue to inform my game moving forward.
FoE is a fast moving game, but the core principles remain the core principles. The core principles taught in CR's guide will never change. Nor will the core principles taught in Dulahan's guide. Based on these core principles, I built cities that maximize FPs, maximize RQs from collections of every building in my city, with an Arc 80 that will give me as many additional riches as I'm willing and able to spend the time to go after. Guide, no guide, those key principles will never be outdated and will stand as long as FoE is played.
