Railroad Tycoon II
Not it is the free software or open source version of this game, but OpenLoco https://openloco.io/ is great, and I hope that this game in near future will have a free assets like as OpenTTD https://www.openttd.org/ .

6 free games updated in the last 60 days
#6 - OpenTTD - Transport Tycoon Deluxe... with multiplayer.... it has the most Win98 Interface, but once you get past that... this is the best and most amazing free sim tycoon game you will ever find.

Love the game, but- I dont have 30$
OpenTTD is awesome and comes up quite often if you search for "free alternative" in this sub.

OpenTTD is quite similar and free. (Free as in freedom and free as in beer.)

Love(ed) that game.
Always wonder where they get their "recruits", who seem to have trouble with aiming their weapons towards the enemy.
There's an open-source & cross platform remake of the engine. You still need the original game assets.
Easy to mod - he config files are YAML.

A littel guide for alien colony assaults in TFTD
(Before I say anything I just want to say that I've only played TFTD on beginner. I don't know if this works on the harder difficulties, but I feel like the strategy is relatively sound. Please don't take my word as gospel lol. Also, PLEASE USE OPENXCOM! It's a lifesaver.)

Is the original Xcom games worth playing nowadays?
If you want to go for that ride I highly recommend to buy the game and install OpenXCom which comes with full compability on modern systems and QoL improvements and a ton of mods and bugfixes (note you need a copy of the original to play openxcom as it uses the sprites, music etc.): https://openxcom.org/

What game gives you nostalgia and how old are you?
X-Com was just so hard, and I kept naming all my soldiers various family and friend names ... and boy did they die a lot. I still go back and play it randomly to this day, thanks to the https://openxcom.org project 🤘🤘🤘

Save 100% on Warhammer 40,000: Gladius
Are you talking about this? That's a homage to the original X-COM games, not the two revived XCOM games (Enemy Unknown and 2).
- An ironman victory almost 30 years in the making. What a journey. What a game. Unlike anything else.

What is your favorite open source Linux game? Mine is Wideland (Best way to describe is the way Settlers 3 should have been)
With the amount of streams I have with modded openxcom, I'm pretty sure I'm already addicted to it.

Et indblik i pirateri af computerspil 90’erne
Til dem der ikke er færdig med at spille UFO: Enemy Unknown, så er der ret meget at hente i OpenXcom. Spil var bare bedre dengang.
